Iterative One Pot Reactions of a Chiral Sulfamidate with 2,4,6-Trichloropyridine: Regiocontrolled Synthesis of Linear and Angular Chiral Dipyrrolidino Pyridines
摘要:
The product of the ring opening of a chiral sulfamidate with the 3-lithiopyridine species obtained by deprotonation of 2,4,6-trichloropyridine with n-BuLi can be deprotonated again in situ with n-BuLi and reacted with a second equivalent of the sulfamidate furnishing a bis beta-aminoethyl pyridine derivative which can be cyclized regioselectively to linear or angular chiral dipyrrolidino pyridines.
