Reactions of N-(2-chloroacetyl)-α-amino acids with 3-cyanopyridine-2(1H)-thiones. New promising route to 3,4- dihydropyrido[3′,2′:4,5]thieno[3,2-e][1,4]diazepine-2(1H),5-diones

, p. 2197 - 2202 (2003)

The reactions of N-(2-chloroacetyl)-α-amino acids with 3-cyanopyridine-2(1H)-thiones afforded N-(3-ammothieno[2,3-b]pyridin-2- ylcarbonyl)-α-amino acids. Heating of the latter smoothly produced 3,4-dihydropyrido[3′,2′:4,5]thieno[3,2-e][1,4]diazepine-2(1H), 5-diones in high yields.
