Abstract

Pyrrolidinyl-camphor derivatives have been proven to be efficient organocatalysts for enantioselective conjugate addition of ketones to alkylidene malonates, affording high chemical yields (up to 95 %) of the corresponding products with high to excellent levels of diastereoselectivity (up to >99:1 dr) and enantioselectivity (up to 96%ee) under solvent-free reaction conditions at ambient temperature.
