Reaction of lithioamino anions with α-oxoketene dithioketals: An improved and a new general method for the synthesis of α-oxoketene S,N- and N,N-ketals

Singh, Okram Mukherjee,Junjappa, Hiriyakkanavar,Ila, Hiriyakkanavar

, p. 3561 - 3565 (2007/10/03)

A new method has been developed for the preparation of α-oxoketene S,N- (A) and N,N-(B) ketals starting from α-oxoketene dithioketals by employing mild conditions. Thus, lithioamino anions 2a-c, 4 and 6 are treated with α-oxoketene dithioketals 1 to affor
