A versatile synthesis of alpha and alpha' disubstituted N-hydroxypiperidine and N-hydroxypyrrolidine by consecutive double 1,4-addition of hydroxylamine on the corresponding bis alpha,beta-tinsaturated diester is described. This reaction takes place an environmentally friendly (ethanol/water) system and at room temperature. (c) 2006 Elsevier Ltd. All rights reserved.
