Compounds of formulae I, II and III:
are disclosed as 5-HT3 inhibitors. The compounds are useful in treating CINV, IBS-D and other diseases and conditions.
Enantiopure 3-substituted morpholines were assembled through ring-opening of a N-2-benzothiazolesulfonyl (Bts) activated aziridine with organocuprates followed by a ring annulation reaction with a vinylsulfonium salt under microwave conditions. Deprotection of the N-Bts group proceeds under very mild conditions with 2-mercaptoacetic acid and LiOH at rt.

A new class of 2-substitutedbenzoxazole carboxamides are presented as potent functional 5-HT3 receptor antagonists. The chemical series possesses nanomolar in vitro activity against human 5-HT3A receptors. A chemistry optimization program was conducted and identified 2-aminobenzoxazoles as orally active 5-HT3 receptor antagonists with good metabolic stability. These novel analogues possess drug-like
