A convenient and improved procedure for the cyanation of enamines and 1,3-dicarboxyl compounds
Buttke,Niclas
, p. 3241 - 3248 (1994)
The direct cyanation of enamines 2a-f using acylsubstituted cyanatobenzenes 1a-c and cyanatoanthraquinone 1d furnishes β-cyanoenamines 3a-f which upon hydrolysis afford the cyanoketones 4a,b. 2-Cyano-1,3-diketones 6a-c are obtained starting from compounds
