The first organocatalytic enantio- and diastereoselective 1,3-dipolar cycloaddition of azomethine ylides with nitroalkenes.
[摘要]:The first chiral thiourea-catalyzed stereoselective 1,3-dipolar cycloaddn. of azomethine ylides with nitro alkenes afforded highly substituted pyrrolidines with high diastereoselectivities of up to >99:1 dr and moderate enantioselectivities.
