Cycloaddition of Chiral tert-Butanesulfinimines with Trimethylenemethane
摘要:
The cycloaddition of chiral tert-butanesulfinimines with trimethylenemethane is found to give facile access to methylene-pyrrolidines with good yields and diastereoselectivities. The full scope of the cycloaddition is explored, and a range of transformations of the formed methylenepyrrolidines to give a range of functionalized chiral pyrrolidines is presented.
