A general and effectivepalladium 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 alkenyltosylates 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.
