Substituents-Controlled Divergent Cyclization Reactions of Benzo[c][1,2]dithiol-3-ones and Hexahydro-1,3,5-triazines

An unprecedented metal-free divergent cyclization reaction of benzo[ c ][1,2]dithiol-3-ones with hexahydro-1,3,5-triazines to assemble six- and eight-membered N-containing heterocycles has been developed.
