The synthesis of 1,1′-disubstituted bis-cyclopropanes by the reaction of substituted propargylic alcohols with CH2I2–R3Al
摘要:
A new efficient method for the synthesis of 1,1'-disubstituted bis-cyclopropanes is described, which involves treatment of 2-alkyn-1-ols with trialkylaluminium and diiodomethane. (C) 2009 Published by Elsevier Ltd.
