The discovery and optimization of novel pyrrolo[3,4-b]pyridin-7(6H)-one MCH-R1 antagonists are described. A systematic SAR study probing the effects of aryl-, benzyl- and arylthio-substituents at the 2-position of the pyrrolo[3,4-b]pyridin-7(6H)-ones led to identification of the 2-[(4-fluorophenyl)thio] derivative 7b as a highly potent MCH-R1 antagonist. This compound also has favorable pharmacokinetic
描述了新型吡咯并[3,4- b ]吡啶-7(6 H)-1 MCH-R1拮抗剂的发现和优化。一项系统的SAR研究探索了吡咯并[3,4- b ]吡啶7-7 (6 H)-1的2位上的芳基,苄基和芳硫基取代基的作用,从而鉴定了2-[(( 4-氟苯基)硫基]衍生物7b作为高效的MCH-R1拮抗剂。该化合物还具有良好的药代动力学特性,具有较高的代谢稳定性,并且对CYP亚型和hERG的影响最小。

Alcohols are among the most abundant and readily available organic feedstocks in industrial processes. The direct catalytic functionalization of sp3 C–O bonds of alcohols remains the main challenge in this field. Here, we report a copper-catalyzed synthesis of benzyl-, allyl-, and allenyl-boronates from benzylic, allylic, and propargylic alcohols, respectively. This protocol exhibits a broad reaction

Mild cross-coupling reaction between benzylboronic esters with carbonylcompounds and some imines was achieved under visible-light-induced iridium-catalyzed photoredox conditions. Functional group tolerance was demonstrated by 51 examples, including 13 heterocyclic compounds. Gram-scale reaction was realized through the use of computer-controlled continuous flow photoreactors.

the construction of a wide variety of trisubstituted stereocenters through a catalytically accessed common chiral intermediate could prove highly enabling for the field of synthetic chemistry. We report the discovery of enantioselective, catalytic 1,2-boronate rearrangements for the synthesis of α-chloro pinacol boronic esters from readily available boronic esters and dichloromethane. The chiral building
