Theoretical study of [4+2] cyclocondensation of N,N-dimethyl-N-(3-oxocyclohexe-1-enyl)-formamidine with substituted and bromo-activated 9Hcarbazole1,4-dione A theoretical study of hetero-Diels-Alder reaction between N,N-dimethyl-N-(3-oxocyclohexe-1-enyl)-formamidine (aza-diene) and substituted 9H-carbazole-1,4-dione. This reaction is regioselective and is an effective method for synthesizing calothrixin B and its analogues. The rich-electron substituted dienophiles permit to acces to the major adducts. The theoretical results are consistent with experience.
