An enantioselectiveelectrophilicamination of α-substituted cyanothioacetates with azodicarboxylate is demonstrated using an axiallychiralguanidine as a chiral Brønsted base catalyst. The corresponding product, having a quaternary stereogenic center at the α-carbon atom, is formed in excellent enantioselectivity.
