摘要
Methyl propiolate undergoes Lewis acid catalyzed reactions with alkenes in high yield. Mono-and 1, 2-disubstituted alkenes give mainly cyclobutenes. 1, 1-Disubstituted, trisubstituted, and tetrasubstituted alkenes give only ene adducts. Use of ethylaluminum dichloride as catalyst allows the isolation of pure products from acid-sensitive alkenes. Functionalized alkenes containing nonbasic functional groups are suitable substrates. Alkenes containing more basic functional groups are suitable if 2 equiv of catalyst is used. © 1979, American Chemical Society. All rights reserved.
