Di- tert-butyl Peroxide-Mediated Radical C(sp2/sp3)-S Bond Cleavage and Group-Transfer Cyclization

A novel strategy of cascade radical C(sp2/sp3)-S bond cleavage and group-transfer cyclization is disclosed. Triggered by alkyl radicals, varieties of 2-isocyanoaryl thioethers containing aliphatic, aryl, and heteroaromatic groups can be cleaved and precisely reinstalled to give benzothiazole derivatives. Mechanistic studies reveal that the cascade reaction undertakes an intermolecular pathway, and the inner radical sources (R radicals) exhibit high priority over those of methyl radical origin from di-tert-butyl peroxide.

The invention relates to a thiourea as the sulfur source synthesis of substituted 2 - aryl benzo thiazole

The invention discloses a method for synthesizing poly-substituted 2-aryl benzothiazoles by utilizing thiourea as a sulphur source. According to the method, thiourea reacts with benzyl chloride to generate an S-benzylisothiourea salt in situ. After that, through the aromatic nucleophilic substitution reaction of the obtained S-benzylisothiourea salt with 2-fluoronitrobenzene and then the one-step reduction (one-pot reaction) process, o-amino phenyl benzyl thioether as an intermediate product can be obtained. Finally, through the iron-catalyzed cross-dehydrogenative-coupling reaction of the o-amino phenyl benzyl thioether, a target product can be obtained. Compared with the traditional synthetic method, the method has the significant advantages of (1) short reaction step, wherein the target product can be synthesized through only three steps of simple reactions by utilizing simple chemical raw materials; (2) mild reaction condition, high atom economy, and relatively safe and cheap reaction reagents; (3) high reaction yield, good substrate tolerance and free of any dangerous or high-toxicity reagent. Therefore, the method might be applied to the large-scale production.
