A compound having the general structure of Formula (I):
or a pharmaceutically acceptable salt, solvate, or ester thereof, is useful in treating diseases, disorders, or conditions such as obesity, metabolic disorders, addiction, diseases of the central nervous system, cardiovascular disorders, respiratory disorders, and gastrointestinal disorders.
The Reformatskyreaction of ethyl bromodifluoroacetate to α-oxygenated sulfinylimines is described. Using Honda–Reformatsky conditions, the reaction proceeds with double diastereodifferentiation, with the configuration of the sulfinyl group determining the stereochemical course of the reaction. Excellent diastereoselectivities (>94:6) are obtained for the matched cases. In contrast, reaction with sulfinylimines

trans-3-hydroxy-L-pipecolic acids are synthesized from a common chiral intermediate 7 by a short and flexible route. The stereospecific inversion of C-3 was achieved by the formation of an oxazoline followed by acidic ring cleavage. The overall yields are 27 % and 30 %, respectively, in 12 and 10 linear steps. Several versatile chiral building blocks are also accessible by this diastereodivergent synthesis. Unlike the
