Several vinylepoxides have been prepared and subjected to a TsOH·H2O-catalyzed aminolysis reaction to afford the corresponding aminoalcohols in good yields. The nucleophilic addition is stereospecific and proceeds with high regioselectivity at the allylic position, unless other stereoelectronic effects competes. The aminolysis reaction is sensitive to steric hindrance at or in the proximity of the
Di- and trisubstituted vinylepoxides in NH4OH were subjected to microwave irradiation affording the corresponding vicinal aminoalcohols in high yields. The reaction is stereospecific and highly regioselective for addition at the allylic carbon. (C) 1999 Elsevier Science Ltd. All rights reserved.
