Abstract

A novel chiral spiro-pyrrolidine silyl ether organocatalyst has been designed. Its catalytic asymmetric effect is demonstrated by the Michael addition reaction, which affords the desired products with an all-carbon quaternary center in up to 99% ee and 87% yield. Furthermore, the reaction process has been investigated via in situ NMR experiments. [ABSTRACT FROM AUTHOR]
