Novel synthesis of 1,3,4-thiadiazine derivatives and their cycloaddition reactions
Wardakhan, Wagnat W.
, p. 608 - 615 (2007/10/03)
4-Phenyl-3-thiosemicarbazide 1 reacted with the α-halocarbonyl compounds 2a, b to give the thiosemicarbazone derivatives 3a, b. The latter compounds underwent cyclization to the 1,3,4-thiadiazine derivatives 4a, b which underwent [2 + 4] cycloaddition rea
