Dienes, bearing an electron-withdrawing substituent at C-1, are cyclopropanated regio-and stereoselectively at the C C double bond proximal to this electron-withdrawing group. The highest selectivity is observed in the case of dienylboronates. The cyclopropanation of these substrates affords almost
