Abstract
N,N-dialkyl-N′-chlorosulfonyl chloroformamidines 1 reacted with 4-substituted urazoles 2 to give [1,2,4]triazolo[1,2-b][1,2,3,5]thiatriazoles 3 in a selective 1,2-NN dinucleophilic mode of reaction. The reaction of 1 with N
1-substituted pyrazol-5-ones 4 afforded pyrazolo[4,3-e][1,4,3]oxathiazines 5 via selective 1,3-CCO dinucleophilic substitution. Compounds 3 and 5 were the sole products isolated from the respective reactions and both represent new ring systems.
