  A quick and flexible synthetic approach to enureas (alkenyl ureas) via the Pd-catalyzed C–N coupling reaction of alkenyl tosylates and mesylates

  摘要：

  我们坚持不懈地探索 Pd 催化 CâN 偶联的化学性质，在此过程中，我们开发了一种催化剂体系，用于烯基甲苯磺酸盐或甲磺酸盐与多种脲的偶联反应。该催化剂体系具有出色的官能团耐受性，可通过 Pd 催化 CâN 偶联反应快速合成整个系列的脲类似物，且收率极高。

  A general and effective palladium system for Suzuki-Miyaura coupling of alkenyl electrophiles under mild reaction conditions is reported. With the Pd(OAc)(2)/CM-phos system, a variety of alkenyl tosylates are coupled well with ArB(OH)(2). Moreover, the first successful examples of using alkenyl mesylates in alkenylation are also described.

  This invention provides compounds that are antagonists of melanin concentrating hormone receptor-1 (MCH-R1). The compounds are represented by formula (I): where m is zero or one, n is zero to two, Y is oxygen or -N (R9)-, R1, R2, R3, R4, R5, R9, and Ring A are defined in the specification. Coumarin and quinolone compounds where R1 and R2 together form a fused benzo ring are preferred. The invention also provides compounds of formula (VI) where the coumarin moiety is replaced by a quinazolinone ring. The compounds are useful for treating MCH-R1-related disorders, particularly overweight conditions including obesity.

  As part of our persistent exploration to elucidate the chemistry of Pd-catalyzed C–N coupling, a catalyst system for the coupling reaction of alkenyl tosylates or mesylates with a variety of ureas has been developed. This catalyst system boasts outstanding functional group tolerance and enables the quick synthesis of the entire series of enurea analogs via Pd-catalyzed C–N coupling reactions in excellent yields.
