“…1,3 Conjugate addition of carbon nucleophiles (Michael addition) to the readily available maleimide scaffold constitutes a straightforward and attractive route for quickly accessing 3-alkylated succinimides. [8][9][10][11] However, there is a distinct lack of suitable nucleophiles for the C]C bond allylation of maleimide derivatives. Common organometallic allyl nucleophiles such as magnesium, 12 silicon, 13 boron, 14 indium, 15 and tin 16 reagents all selectively provide the 1,2-adduct of direct carbonyl addition, rather than 3-allylated succinimide derivative resulting from 1,4-addition.…”
