Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 97739-46-3, is researched, Molecular C16H21O3P, about Complex Polyheterocycles and the Stereochemical Reassignment of Pileamartine A via Aza-Heck Triggered Aryl C-H Functionalization Cascades, the main research direction is benzo spiro fused polyheterocycle preparation; alkenyl carbamate aminoarylation aza heck cyclization tandem reaction; pileamartine A stereochem reassignment.Reference of 1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane.
Structurally complex benzo- and spiro-fused N-polyheterocycles can be accessed via intramol. Pd(0)-catalyzed alkene 1,2-aminoarylation reactions. The method uses N-(pentafluorobenzoyloxy)carbamates as the initiating motif, and this allows aza-Heck-type alkene amino-palladation in advance of C-H palladation of the aromatic component. The chem. is showcased in the first total synthesis of the complex alkaloid (+)-pileamartine A, I, which has resulted in the reassignment of its absolute stereochem.
This literature about this compound(97739-46-3)Reference of 1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantanehas given us a lot of inspiration, and I hope that the research on this compound(1,3,5,7-Tetramethyl-6-phenyl-2,4,8-trioxa-6-phosphaadamantane) can be further advanced. Maybe we can get more compounds in a similar way.
