Organocatalytic asymmetric allylic alkylation of oxindoles with Morita–Baylis–Hillman carbonates

Abstract

The organic Lewis base-catalysed asymmetric allylic alkylation of 3-substituted oxindoles with Morita-Baylis-Hillman carbonates is reported, affording multifunctional oxindoles with adjacent quaternary and tertiary chiral centres (dr up to 92 : 8, 86-97% ee).
