Abstract
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 afford the corresponding S,N-ketals 3a-j, 5a-j, 7a-e and N,N-ketals 8a,b in good yields. The scope and steric orientations of the reaction have been investigated.
