摘要: Abstract A versatile route to β-enamino esters 1, using accessible starting materials, was developed. Lithiated enamines are allowed react with diethyl carbonate or benzyl chloroformate the formation of 1a 1b. The reaction is rather general from a wide array ketimines and aldimines. Products included cyclic 1aa-ac, very useful for synthesis natural products.
