## Abstract A new __Lewis__ base catalyzed aldol reaction of trimethylsilyl enolates with aldehydes is established in DMF or pyridine solvent by using a __Lewis__ base such as lithium diphenylamide (__Tables 4__ and __5__) or lithium 2‐pyrrolidone (__Tables 6__–__8__). The effect of solvent suggest
## Abstract Aldol reactions between trimethylsilyl ketene acetals and aldehydes by using a catalytic amount of alkoxide anion proceeded smoothly to afford the corresponding aldols in DMF, indicating that the initially‐formed aldolate anion effectively worked to catalyze the reaction. The “product‐c
