Abstract
Synthesis of janusene (5, 5a, 6, 11, 11a, 12-hexahydro-5, 12:6, 11-di-o-benzenonaphthacene) requires several reaction steps, starting from anthracene. In this account, a one-pot, three-step synthesis of janusene N-methyl-5a, 11a-dicarboximide employing 2, 3-dibromo-N-methylmaleimide as an acetylene equivalent is described. This thermal reaction is a simple synthetic procedure in comparison to sequential-multi step [4+2] cycloaddition routes. Here, 2, 3-dibromo-N-methylmaleimide acts effectively as a ‘molecular glue’, bridging two anthracene molecules together.
