Abstract

The formation of optically active nitrones from a l-prolin­e catalyzed aldol reaction of aldehydes with activated carbony­l compounds and an in situ reaction with hydroxylamines is presente­d. The reaction gives optically active N-alkyl-C-β-hydrox­y-nitrones in high yield and with up to 96% ee.
