(8r)-3-[(4r,5s)-4-hydroxy-5-(hydroxymethyl)oxolan-2-yl]-4h,7h,8h-imidazo[4,5-d][1,3]diazepin-8-ol

Description

(8R)-3-[(4R,5S)-4-hydroxy-5-(hydroxymethyl)oxolan-2-yl]-3H,4H,7H,8H-imidazo[4,5-d][1,3]diazepin-8-ol belongs to the class of organic compounds known as imidazodiazepines. These are organic compounds containing an imidazole ring fused to a diazepine ring. Imidazole is 5-membered ring consisting of three carbon atoms, and two nitrogen centers at the 1- and 3-positions. Diazepine is a 7-membered ring consisting of five carbon and two nitrogen atoms. Based on a literature review very few articles have been published on (8R)-3-[(4R,5S)-4-hydroxy-5-(hydroxymethyl)oxolan-2-yl]-3H,4H,7H,8H-imidazo[4,5-d][1,3]diazepin-8-ol.
