Syntheses of 9-Phenylsulfonylimino-1,4-dioxa-8,10-diazacyclotridecanes and 9,22-Bis(phenylsulfonylimino)-1,4,14,17-tetraoxa-8,10,21,23-tetraazacyclohexacosanes: Macrocyclization via Dimethyl N-Phenylsulfonylcarbonimidothioates

Article abstract of DOI:10.1246/bcsj.66.148

The reaction of dimethyl N-phenylsulfonylcarbonimidodithioates (1) with diamines gave three different types of products due to changes in the molar ratio of the starting materials.From aliphatic diamines heterocyclic 1:1 and acyclic 2:1 reaction products
