For asymmetric synthesis of α-methyl-β-amino units using catalytic enantioselective Mannich reactions of simple imines with enolate components, only one example was reported to the best of our knowledge, but regioselectivity was moderate (see ref. [10c]).

anti-Selectivity was remarkable because syn- and anti-selectivity was observed in the reactions of α-tert-butyldimethylsilyloxy and α-benzyloxy ketene silyl acetals, respectively. It was reported in aldol reactions that syn-selectivity was obtained in the reactions of propionate components and α-tert-butyldimethylsilyloxy ketene silyl acetals, while only α-benzyloxy ketene silyl acetals gave anti-adducts: T.
