Direct Amino-Crotylsilylation of Achiral Acetals and Aldehydes: Asymmetric Synthesis of Homoallylic Amines and Functionalized Pyrrolidines
摘要:
The condensation between chiral (E)-crotyl-silanes 1 and in situ-generated achiral N-acylimines produces homoallylic N-acylamines 3 or tetrasubstituted N-acylpyrrolidines 4 with high levels of diastereoselection.
