Water mediated and environmentally friendly, step-wise, tandem & one-pot syntheses of 2-(1H-benzo[d]imidazole-2-yl)-N-arylbenzamide derivatives have been developed by simply combining phthalic anhydride, anilines and phenylenediammonium dihydrogenphosphate. This reaction has an easy workup, provides excellent yields, and uses water as the solvent which is considered to be relatively environmentally benign.

Anhydrides 1, 6 and 10 have been reacted, independently, with aromatic primary amines 2 in solid phase by simple physical grinding of reactants with p-toluenesulphonicacid as a catalyst to yield corresponding open chain derivatives, monoacid monoamides3,7 and 11 respectively. The latter have each been transformed into the corresponding cyclic derivatives, i.e. imides 5, 9 and 13 respectively in solid phase by simple physical grinding of each with K 2CO3, alkylating agent and tetrabutylammoniumbromide as a catalyst with short reaction times. These cyclic imides can also be obtained by physical grinding of each of 3, 7 and 11 with dicyclohexylcarbodimide as a dehydrating agent in solid phase.
Indoloquinones, Part 6.13 First palladium-mediated oxidative cyclization of arylamino-1,2-benzoquinones to carbazole-3,4-quinones - Application to the total synthesis of carbazoquinocin C and (±)- carquinostatin A
Kn?lker, Hans-Joachim,Reddy, Kethiri R.
, p. 596 - 598 (2007/10/03)
A highly convergent synthesis of the carbazole-3,4-quinone alkaloids carbazoquinocin C and (±)-carquinostatin A is reported using a palladium- mediated oxidative coupling of arylamines and substituted 1,2-benzoquinones.
