Photochemical synthesis of highly functionalized cyclopropyl ketones

A series of di- and trisubstituted cyclopropyl ketones 11 were prepared by irradiation of ketones 3 and 5, which bear a leaving group adjacent to the carbonyl C-atom. The required ketones 3 could be easily synthesized either by functionalization of ketones 1 with a hypervalent iodine reagent, 2, or by O-sulfonylation of alpha-hydroxy ketones 7. The nitrates 5 were obtained by treatment of the corresponding alpha-bromo ketones with AgNO3. The irradiation of 3 and 5 must be performed in the presence of an acid scavenger (1-methyl-1H-imidazole) to obtain the cyclopropanes 11 in good yields. The synthetic efficiency of the method was, among other things, demonstrated by the preparation of a highly strained bicyclo[2.1.0]pentane 11i in good yield. The mechanism of the photochemical cyclization was investigated by means of photokinetic measurements, as well as by quantum-chemical calculations. It was shown that the presence of the leaving group substantially influences all steps of the photochemical reaction cascade. The X-ray crystal structures of 11j and exo-11k were also determined.

4-Oxo-1,4-dihydropyridines as selective CB2 cannabinoid receptor ligands part 2: Discovery of new agonists endowed with protective effect against experimental colitis

Further on to our earlier work on the 4-oxo-1,4-dihydropyridine, we describe herein our strategy to get access to potent selective CB2 receptor agonists. Thus, we designed and synthesized 29 compounds, evaluated on both hCB1 and hCB2 cannabinoid receptors, and assessed 11 of them in the TNBS-induced colitis model in mice. Compound 48 was found to be the most efficient of our series, exhibiting an exquisite protection against experimental colitis, superior to the one observed after treatment with Pentasa.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.SDS of cas: 65412-03-5, you can also check out more blogs about65412-03-5

A new procedure for highly stereoselective and regioselective synthesis of 2-ethynyl-3-hydroxytetrahydropyran derivatives based on alkyne-Co2(CO)6 complex

Treatment of trans-epoxides 3 with Co2(CO)8 gave the corresponding cobalt complexes, which were subsequently exposed to a catalytic amount of BF3¡¤OEt2 at -78C to provide exclusively cis-2-ethynyl-3- hydroxytetrahydropyran derivatives via endo mode cyclization pathway. cis- Congeners, cis-3 afforded the corresponding trans tetrahydropyran derivatives exclusively. This novel cyclization has been found to proceed with retention of configuration at the propynyl stereogenic center. Requirement for stereoselectivity in cyclization was discussed.

Catalytic asymmetric intermolecular stetter reaction of enals with nitroalkenes: Enhancement of catalytic efficiency through bifunctional additives

An asymmetric intermolecular Stetter reaction of enals with nitroalkenes catalyzed by chiral N-heterocyclic carbenes has been developed. The reaction rate and efficiency are profoundly impacted by the presence of catechol. The reaction proceeds with high selectivities and affords good yields of the Stetter product. Internal redox products were not observed despite of the protic conditions. The impact of catechol has been found to be general, facilitating far lower catalyst loadings than were previously achievable.

Discovery of a First-in-Class, Potent, Selective, and Orally Bioavailable Inhibitor of the p97 AAA ATPase (CB-5083)

The AAA-ATPase p97 plays vital roles in mechanisms of protein homeostasis, including ubiquitin-proteasome system (UPS) mediated protein degradation, endoplasmic reticulum-associated degradation (ERAD), and autophagy. Herein we describe our lead optimization efforts focused on in vitro potency, ADME, and pharmaceutical properties that led to the discovery of a potent, ATP-competitive, D2-selective, and orally bioavailable p97 inhibitor 71, CB-5083. Treatment of tumor cells with 71 leads to significant accumulation of markers associated with inhibition of UPS and ERAD functions, which induces irresolvable proteotoxic stress and cell death. In tumor bearing mice, oral administration of 71 causes rapid accumulation of markers of the unfolded protein response (UPR) and subsequently induces apoptosis leading to sustained antitumor activity in in vivo xenograft models of both solid and hematological tumors. 71 has been taken into phase 1 clinical trials in patients with multiple myeloma and solid tumors.
