The catalytic hydrogenation of 4-methyl itaconate derivatives bearing a chiral auxiliary and their conjugate reduction with n-Bu3SnH in the presence of Lewis acid were examined to reveal their diastereoselectivity. The homogeneous catalytic hydrogenation of 4-methyl itaconyl (1S)-(−)-2,10-camphorsultam with the Crabtree's catalyst [Ir(COD)(PCy3)(py)]PF6 in CH2Cl2–MeOH (2:1 v/v) gave less polar (1S
