A NEW GENERAL APPROACH TO 2-SUBSTITUTED METHYLENECYCLANES USING 1-(DIALKYLBORYLMETHYL)CYCLOALKENES
A novel method for the synthesis of 2-substituted methylenecyclopentanes and methylenecyclohexanes based on the allylboration of carbonyl compounds and alkoxyacetylenes with 1-(dialkylborylmethyl)cyclopentene and -cyclohexene is described.
