Bidirectional asymmetric allylboration and the synthesis of C₂ symmetric 3-methylenepentane-1,5-diols

Abstract

The double allylboration of aldehydes using 1,3-bis(diisopinocampheylboryl)-2-methylenepropane under Brown’s salt-free conditions provides C₂ symmetric 3-methylenepentane-1,5-diols in excellent enantiomeric excess.
