摘要
A novel stereoselective synthesis of 3-hydroxyazetidines starting from 2,3-hydroxyazetidines starting from 2,3-epoxyamines is described. Regioselectivity of the intramolecular cyclization of 2,3-epoxyamines is controlled by the use of magnesium bromide. The cyclization proceeds with retention of the stereochemistry, caused by double inversion of two sequential S(N)2 reactions of the epoxyamines. (C) 1997 Elsevier Science Ltd.
