Organocatalyzed asymmetric [2+2] cycloaddition of saccharin-derived endocyclic ketimines and allenoates for the synthesis of fused azetidines
We report a novel enantioselective [2 + 2] cycloaddition of allenoate and endocyclic ketimine derived from saccharin, catalyzed by a chiral tertiary amine. The methodology enables the synthesis of fused tricyclic azetidines with a quaternary stereogenic center, exhibiting high enantioselectivity and...
