Abstract
In the presence of BF 3 -OEt 2 (0.2 molar equiv), the reactions (-10 o C, CH 2 Cl 2 ) of N-Cbz-α-amino aldehydes with allyltrimethylsilane produced pyrrolidines in good yields (70-80%), with high all-cis stereoselecti- vity at the C-2, C-3, and C-5 positions, along with small amounts of the expected homoallylic alcohols
