insertion reaction occurs only at the other N-‘alkyl’ unit. In Cα-unbranched diazoamides, the inherent electroniceffects of the N-‘alkyl’ group influence the regioselectivity of the reaction. The N-BTMSM group also influences the conformational preference about the amide N–Cα bond in Cα-branched systems which, in turn, affects the regioselectivity of the reaction; substituent electroniceffects are subtle
