The Mukaiyama aldol type condensation of t-butyldimethylsilyloxypyrrole 1b with methyl 2-formylbenzoate furnished the aldol adduct 9 with high yield and complete stereoselectivity. An erythro (anti) configuration was established (X-ray) in sharp contrast with the reaction of 1b with aliphatic aldehy
Starting from the (R)-(-)-phenylglycinol derivative (I), the stereoselective synthesis of polyhydroxylated pyrrolidines [cf. (VIII)] and the indolizidine (XII) is based on the diastereoselective condensation of the chiral silyloxypyrrole (III) with aldehydes (IV). The preparation of the indolizidine
## Abstract Enantiopure N‐sulfinyl‐δ‐amino‐β‐ketoesters and isoquinolones, prepared from sulfinimines (N‐sulfinyl imines) are a new class of polyfunctionalized chiral building blocks. These building blocks provide easy access to enantiomerically pure, functionalized piperidines and tetrahydroisoqui
## Abstract The domino Mannich/aza‐Michael reaction of γ‐malonate‐substituted α,β‐unsaturated esters with __N__‐protected arylaldimines has been achieved. Catalyzed by bifunctional thioureas, 2,5‐__cis__‐configured polysubstituted pyrrolidines are obtained in good to excellent yields (76–99%), enan
