Substituent-controlled divergent cyclization reactions of benzo[c][1,2]dithiol-3-ones and hexahydro-1,3,5-triazines

Abstract

The first divergent cyclization reactions of benzo[c][1,2]dithiol-3-ones to assemble six- and eight-membered N-containing heterocycles is displayed herein. This unprecedented formal [4+4]/[4+2] cycloadditions of 3H-benzo[c][1,2]dithiol-3-ones and hexahydro-1,3,5-triazines was controlled by the...
