The article was titled 《RhIII-Catalyzed formal [5 + 1] cyclization of 2-pyrrolyl/indolylanilines using vinylene carbonate as a C1 synthon》, and you may find the article in Organic Chemistry Frontiers.Recommanded Product: 872-36-6 The information in the text is summarized as follows:
A rhodium(III)-catalyzed formal C-H [5 + 1] cyclization of 2-pyrrolyl/indolylanilines with vinylene carbonate was explored for synthesis of 4-methylpyrrolo[1,2-a]quinoxalines such as I [R1 = H, 8-OMe, 7-OTs, etc.; R = H, 1,3-di-Me] and 6-methylindolo[1,2-a]quinoxaline such as II [R1 = H, 2-F, 2-Cl; R = H, 9-OMe, 9-Br, etc.]. This established protocol was characterized by an exceedingly simple reaction system and excellent functional group toleration and yields. Most importantly, entirely distinct from documented [4 + 2] cyclization conversions, herein, the emerging vinylene carbonate firstly presented as a C1 synthon to realize [5 + 1] annulation and showed new chem. reactivity. Biol. studies indicated that few of these prepared I and II products were promising candidates in terms of their antibacterial activity. The results came from multiple reactions, including the reaction of Vinylene carbonate(cas: 872-36-6Recommanded Product: 872-36-6)
Vinylene carbonate(cas: 872-36-6) belongs to esters. Alkyl carbonates find applications as solvents for lithium ion battery electrolytes and the use of high quality battery grade electrolytes having extremely low water (<10 ppm) and acid (<10 ppm) contents are critical for achieving high electrochemical performance.Recommanded Product: 872-36-6
