A novel synthesis of di(1-methylazacycloalkeno)[2,3-b:2',3'-d]pyridines through annulation on lactam acetals
Jain,Jain,Singh,Anand
, p. 131 - 134 (2007/10/02)
Annulation reaction of lactam acetals 1a and b with primary amides provided a facile synthesis of di(1-methylazacycloalkeno)[2,3-b:2',3'-d]pyridines 6(a-i). Dehydrogenation of 6a,b,d formed dipyrrolo[2,3-b:2',3'-d]pyridines 7a,b,d.
