Abstract
A scheme for the preparation of novel synthetic reagents, pyrazolyl (e thoxycarbonyl) ketene aminals, from acetyl(ethoxycarbonyl)ketene (N-be nzoyl)aminal via its difluoroboron chelate is suggested. The possibili ty of cyclization of the ketene aminals obtained into functionally sub stituted pyrazolo[1,5-c]pyrimidines is shown.
