## Abstract Catalytic asymmetric Mannichβtype reactions of an Ξ±βhydrazono ester with silicon enolates in aqueous media have been developed by using ZnF~2~ and chiral diamines as catalysts. In these reactions, both Zn^2+^ and a fluoride anion were necessary to achieve high yields and enantioselectiv
