Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Research Support, Non-U.S. Gov’t, Organic & Biomolecular Chemistry called The synthesis of a series of adenosine A3 receptor agonists, Author is Broadley, Kenneth J.; Burnell, Erica; Davies, Robin H.; Lee, Alan T. L.; Snee, Stephen; Thomas, Eric J., which mentions a compound: 97739-46-3, SMILESS is CC1(C2)OC(C3)(C)OC2(C)OC3(C)P1C4=CC=CC=C4, Molecular C16H21O3P, Application of 97739-46-3.

A series of 1′-(6-aminopurin-9-yl)-1′-deoxy-N-methyl-β-D-ribofuranuronamides that were characterized by 2-dialkylamino-7-methyloxazolo[4,5-b]pyridin-5-ylmethyl substituents on N6 of interest for screening as selective adenosine A3 receptor agonists, have been synthesized. This work involved the synthesis of 2-dialkylamino-5-aminomethyl-7-methyloxazolo[4,5-b]pyridines and analogs that were coupled with the known 1′-(6-chloropurin-9-yl)-1′-deoxy-N-methyl-β-D-ribofuranuronamide. The oxazolo[4,5-b]pyridines were synthesized by regioselective functionalization of 2,4-dimethylpyridine N-oxides. The regioselectivities of these reactions were found to depend upon the nature of the heterocycle with 2-dimethylamino-5,7-dimethyloxazolo[4,5-b]pyridine-N-oxide undergoing regioselective functionalization at the 7-Me group on reaction with trifluoroacetic anhydride in contrast to the reaction of 4,6-dimethyl-3-hydroxypyridine-N-oxide with acetic anhydride that resulted in functionalization of the 6-Me group. To optimize selectivity for the A3 receptor, 5-aminomethyl-7-bromo-2-dimethylamino-4-[(3-methylisoxazol-5-yl)methoxy]benzo[d]oxazole was synthesized and coupled with the 1′-(6-chloropurin-9-yl)-1′-deoxy-N-methyl-β-D-ribofuranuronamide. The products, e.g. I, were active as selective adenosine A3 agonists.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Novel Class of Tertiary Phosphine Ligands Based on a Phospha-adamantane Framework and Use in the Suzuki Cross-Coupling Reactions of Aryl Halides under Mild Conditions, published in 2003-03-20, which mentions a compound: 97739-46-3, Name is 1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane, Molecular C16H21O3P, HPLC of Formula: 97739-46-3.

Arylation or alkylation of the 1,3,5,7-tetramethyl-2,4,6-trioxa-8-phospha-adamantane allows for the preparation of sterically hindered tertiary phospha-adamantane phosphines I (R = Ph, 2-MeC6H4, n-C14H29), suitable for use in palladium-catalyzed cross-coupling reactions. For example, use of a catalytic system incorporating Pd2(dba)3 and I (R = Ph) promoted the Suzuki cross-coupling of aryl iodides, bromides, and activated chlorides with a variety of arylboronic acids at room temperature in a few hours with high yields.

Author is Le, Christine M.; Hou, Xiao; Sperger, Theresa; Schoenebeck, Franziska; Lautens, Mark.

Pharmaceutically relevant methylene oxindoles are synthesized by a palladium(0)-catalyzed intramol. chlorocarbamoylation reaction of alkynes. A relatively underexplored class of caged phosphine ligands is uniquely suited for this transformation, enabling high levels of reactivity and exquisite trans selectivity. E.g., in presence of Pd2(dba)3 and 1,3,5,7-tetramethyl-2,4,6-trioxa-8-phenyl-6-phosphaadamantane in toluene, intramol. chlorocarbamoylation of 2-TIPSCCC6H4NBnCOCl gave 96% 3-(chloromethylene)oxindole derivative (E)-I.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane(SMILESS: CC1(C2)OC(C3)(C)OC2(C)OC3(C)P1C4=CC=CC=C4,cas:97739-46-3) is researched.Electric Literature of C5H5BrN2. The article 《Phenylphosphatrioxa-adamantanes: bulky, robust, electron-poor ligands that give very efficient rhodium(I) hydroformylation catalysts》 in relation to this compound, is published in Dalton Transactions. Let’s take a look at the latest research on this compound (cas:97739-46-3).

The cage phosphines 1,3,5,7-tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane (1a) and 1,3,5,7-tetraethyl-6-phenyl-2,4,8,trioxa-6-phosphaadamantane (1b) were made by the acid catalyzed addition of PhPH2 to the appropriate β-diketones; the acid used (HCl, H3PO4 or H2SO4) and its concentration affect the rate and selectivity of these condensation reactions. Phosphines 1a and 1b react with [PdCl2(NCPh)2] to form trans-[PdCl2(1a)2] (2a) and trans-[PdCl2(1b)2] (2b) as mixtures of rac and meso diastereoisomers. The Pt(II) chem. is more complicated and when 1a or 1b is added to [PtCl2(cod)], equilibrium mixtures of trans-[PtCl2L2] and [Pt2Cl4L2] (L = 1a or 1b) are formed in CH2Cl2 solution Meso/rac mixtures of trans-[MCl(CO)(1a)2] M = Ir (6a) or Rh (7a) are formed upon treatment of MCl3·nH2O with an excess of 1a and the anionic Co complex [NHEt3][CoCl3(1a)] (9) was isolated from the product formed by CoCl2·6H2O and 1a. The νCO values from the IR spectra of 6a and 7a suggest that 1a resembles a phosphonite in its bonding to Rh and Ir. Crystal structures of meso-2a, meso-2b, rac-6a and 9 are reported and in each case a small intracage C-P-C angle of ∼94° is observed and this may partly explain the bonding characteristics of ligands 1a and 1b. The cone angles for 1a and 1b are similar and large (∼200°). Rh complexes of ligands 1a and 1b are hydroformylation catalysts with similarly high activity to catalysts derived from phosphites. The catalysts derived from 1a and 1b gave unusually low linear selectivity in the hydroformylation of hexenes. This feature was further exploited in quaternary-selective hydroformylations of unsaturated esters; catalysts derived from 1a give better yields and regioselectivities than any previously reported catalyst.

Reference of 1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane, is researched, Molecular C16H21O3P, CAS is 97739-46-3, about Titanium Complexes of Sterically Demanding Cage-Phosphinimide Ligands.

The known ligand PPh(C6H4O3Me4) (1) and its analog PCy(C6H4O3Me4) (2) have been prepared In the latter synthesis the diphosphine species (PCy)2(C6H2O3Me4) (3) was also isolated as a minor product. Reaction of the cage phosphines 1 and 2 with Me3SiN3 effected oxidation to the corresponding (trimethylsilyl)phosphinimines Me3SiNPR(C6H4O3Me4) (R = Ph (4), Cy (5)). Subsequent reactions afforded the titanium complexes CpTiCl2(NPR(C6H4O3Me4)) (R = Ph (6), Cy (7)) and CpTiMe2(NPR(C6H4O3Me4)) (R = Ph (8), Cy (9)). Preliminary screening for catalytic activity in ethylene polymerization employing either methylalumoxane (MAO) or [Ph3C][B(C6F5)4] as the activator showed minimal catalytic activity. These observations were probed via reactions of these complexes with AlMe3, MAO, or [Ph3C][B(C6F5)4]. Reaction of 8 with AlMe3 gave several products, one of which was fully characterized as the cage-rupture product CpTiMe2(NPCy(C6H4O3Me5)(μ-AlMe2)(AlMe3)) (10). A similar product is inferred by the spectroscopic monitoring of the reaction of 8 with MAO. In contrast, reaction of 2 with AlMe3 resulted only in the formation of the adduct Me3AlPCy(C6H4O3Me4) (11). Structural data are reported for 2, 3, 8, 10, and 11.
