| Abstract | We report a new catalyst system that should enhance the use of enantioselective 1,3-dipolar cycloadditions of azomethine ylides with electronic-deficient olefins in the divergent pathways of diversity-oriented synthesis (DOS). The underlying reaction is of considerable interest in DOS because its stereospecificity enables stereochemical diversification of up to four tetrahedral centers on pyrrolidine rings. This new catalyst system extends the scope and selectivity of the azomethine ylide cycloaddition and is compatible with reagents used in a one-bead/one-stock solution technology platform for DOS. |
