Unusual reaction of allylic systems: homo- and cross-cyclizations leading to four-carbon rings
Siedlecka, Renata
experimental part, p. 2351 - 2355 (2009/07/18)
The reaction of stabilized allylic-type carbocations with electron rich olefins was investigated. In most cases a facile cyclobutane ring formation was observed by [2+2] cycloaddition reaction promoted by Br?nsted or Lewis acids. Some attempts were made t
