On August 20, 2021, Bi, Jingjing; Tan, Qiang; Wu, Hao; Liu, Qingfeng; Zhang, Guisheng published an article.Formula: C12H16O7 The title of the article was Rhodium-Catalyzed Denitrogenative Trans-annulation of N-Sulfonyl-1,2,3-triazoles with Glycals Giving Pyrroline-Fused N-Glycosides. And the article contained the following:
Described here is a selective synthesis of 2,3-dihydropyrrole-fused N-glycosides through rhodium-catalyzed denitrogenation trans-annulation of N-sulfonyl-1,2,3-triazoles with glycals. A series of pyrroline-fused N-glycosides are afforded in moderate to excellent yields with exclusive regioselectivity and stereoselectivity. Functional application of such a resultant product by oxidative addition and epoxidation is also explored. Notably, the treatment of a pyrroline-fused N-glycoside (3a) with TMSOTf efficiently leads to an interesting unexpected C-nucleoside I via a TMSOTf-inducing ring opening/acetyl migration/ring closing reaction sequence. The experimental process involved the reaction of (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate(cas: 2873-29-2).Formula: C12H16O7
The Article related to crystal structure aminoglycoside stereoselective cyclization sulfonyl triazole glycal, stereoselective cyclization aminoglycoside preparation rhodium catalyzed sulfonyl triazole glycal, aminoglycoside preparation rhodium catalyzed annulation sulfonyl triazole pyrroline glycoside and other aspects.Formula: C12H16O7
