Abstract
AbstractA highly regio‐ and stereoselective protocol for the synthesis of vicinal quaternary and tertiary stereocenters has been developed. The 6′‐OH Cinchona alkaloids (BnCPN or BnCPD) at low catalyst loading (0.5–5 mol%) catalyze the Michael addition of trisubstituted carbon nucleophiles to nitrodienes in good to excellent yield (up to >99), high enantioselectivity (up to 99% ee) and high diastereoselectivity (up to >99:1 dr) under mild reaction conditions.
