On January 17, 2020, Chen, Kai-Chi; Barve, Indrajeet J.; Sun, Chung-Ming published an article.Formula: C7H6ClNO2 The title of the article was Catalyst-Controlled Regioselective Synthesis of Benzotriazolodiazepin-7-ones and Benzotriazolodiazocin-8-ones. And the article contained the following:
A catalyst-controlled highly chemoselective and regioselective intramol. cycloamidation of triazol-1-ylbenzamides toward the synthesis of scarcely known heterocycles is reported. In the presence of a palladium catalyst, this cycloisomerization reaction afforded substituted benzotriazolodiazepin-7-ones via intramol. insertion of a palladium into C-C triple bond in a 7-exo-dig way. Alternatively, the use of a silver catalyst in the reaction produced substituted benzotriazolodiazocin-8-ones in a highly regioselective manner through 8-endo-dig intramol. ring closure. The experimental process involved the reaction of 2-Amino-4-chlorobenzoic acid(cas: 89-77-0).Formula: C7H6ClNO2
The Article related to palladium catalyst triazolylbenzamide diastereoselective chemoselective regioselective intramol cycloamidation, benzotriazolodiazepinone preparation, silver catalyst triazolylbenzamide diastereoselective chemoselective regioselective intramol cycloamidation, benzotriazolodiazocinone preparation and other aspects.Formula: C7H6ClNO2
