Chen, Yuncan published the artcileSynthesis of 2-aminothiazoles via rhodium-catalyzed carbenoid insertion/annulation of sulfoxonium ylides with thioureas, Name: 4-(Naphthalen-1-yl)thiazol-2-amine, the publication is Chinese Chemical Letters (2021), 32(8), 2555-2558, database is CAplus.
Sulfoxonium ylides as carbene precursors couple smoothly with thioureas in the presence of 5 mol% of rhodium(II) acetate dimmer via carbenoid insertion to afford the corresponding 2-aminothiazoles with high chemoselectivity, provided a facile and efficient approach to access a variety of 2-aminothiazole derivatives with good functional groups tolerance.
Chinese Chemical Letters published new progress about 56503-96-9. 56503-96-9 belongs to thiazole, auxiliary class Thiazole,Amine,Naphthalene, name is 4-(Naphthalen-1-yl)thiazol-2-amine, and the molecular formula is C13H10N2S, Name: 4-(Naphthalen-1-yl)thiazol-2-amine.
