Synthesis of sulfur heterocycles via domino metal-mediated reactions
Castanheiro, Thomas,Suffert, Jean,Donnard, Morgan,Gulea, Mihaela
, p. 162 - 165 (2017/01/22)
Two methodologies to access S-heterocycles and mixed N,S-heterocycles via metal-mediated domino reactions are described. One involves a cyclocarbopalladation/cross-coupling domino process and leads to benzene-fused five- or six-membered sulfur heterocycles with a stereo defined tetrasubstituted exocyclic double bond. The other consists in a three-component domino reaction between 2-aminophenyl disulfide, copper cyanide, and an electrophile to access N-substituted 2-amino benzothiazoles. Preliminary results in the use of the second method to access N-substituted 2-imino benzothiazoles are also reported.

At this circumstance for the first time, a facile and convenient method for heteroaryl ureas has been developed via a two-step process involving in situ C-OH activation followed by palladium catalyzed C-N coupling of heteroarenols with ureas, which show excellent functional group tolerance and give out rapid coupling in good to excellent yield.

N-Aryl-N',N"-bis(benzothiazol-2-yl)guanidines have been obtained by the reaction of N-aryl-N'-benzothiazol-2-ylthioureas (1) with lead oxide.Oxidative cyclisation of N-aryl-N',N"-bis(benzothiazol-2-yl)guanidines (2) by lead tetraacetate led to the formati
