The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 1,2-Benzisoxazole( cas:271-95-4 ) is researched.Category: ruthenium-catalysts.Lei, Xiaoqiang; Gao, Mohan; Tang, Yefeng published the article 《Rh(II)-Catalyzed Transannulation of N-Sulfonyl-1,2,3-Triazoles with 2,1-Benzisoxazoles or 1,2-Benzisoxazoles》 about this compound( cas:271-95-4 ) in Organic Letters. Keywords: rhodium catalyzed transannulation sulfonyltriazole benzisoxazole; quinazoline imidazole preparation sulfonyltriazole transannulation cycloaddition. Let’s learn more about this compound (cas:271-95-4).
A Rh(II)-catalyzed transannulation of N-sulfonyl-1,2,3-triazoles with 2,1-benzisoxazoles has been developed, which affords an efficient method for the synthesis of quinazoline derivatives The transformation represents an unprecedented example which utilizes N-sulfonyl-1,2,3-triazole as an aza-[2C]-component in cycloadditions Meanwhile, a Rh(II)-catalyzed formal [3 + 2] cycloaddition of N-sulfonyl-1,2,3-triazoles with 1,2-benzisoxazoles is also presented, which enables the rapid synthesis of functionalized imidazole derivatives
