โœฆ Synopsis

Nevertheless there is a surprising exiguity in certain areas, such as the alkylation of 4,-5,6,7-tetrahydroindazolin-3-one (1). The differentiation between (2) and (II), and their properties, has been hampered by inadequate synthetic methods and by doubts regarding the authenticity of structural assignments.

The cyclization of 4-aryl-1-arylsulfonylthiosemicarbazides 3, which were prepared by treatment of arylsulfonyl chlorides 1 with 4-aryl-3-thiosemicarbazides 2, with chloroacetyl chloride, provided the corresponding 2-arylamino-4-arylsulfonyl-4H-1,3,4-thiadiazin-5(6H)-ones 4 in good yields. The struct
