CAS NO.: 32647-67-9;(1R,2R,4S)-2-((R)-1,2-dihydroxyethyl)-3,6-diphenylbicyclo[2.2.0]hexane-1,2,4,5-tetraol. PROPERTIES: This complex chiral polyol presents as a white crystalline solid with a molecular weight of approximately 366.4 g/mol. The (1R,2R,4S)-2-((R)-1,2-dihydroxyethyl)-3,6-diphenylbicyclo[2.2.0]hexane-1,2,4,5-tetraol combines multiple hydroxyl groups with a bicyclic framework and phenyl substituents. It exhibits limited aqueous solubility but good dissolution in lower alcohols and DMSO. Stability characterization reveals sensitivity to oxidative degradation and acid-catalyzed glycoside hydrolysis of the polyol groups, necessitating storage at 2-8 degree Celsius in sealed glass containers. Handlers should use powder hoods with HEPA filtration and wear cut-resistant gloves during handling. Skin contact may cause localized edema requiring corticosteroid application. Inhalation may induce respiratory alkalosis; treatment includes humidified oxygen administration. Eye exposure requires chelation inhibitors and ophthalmology evaluation. Waste should be hydrolyzed with dilute acid prior to disposal. APPLICATIONS: The (1R,2R,4S)-2-((R)-1,2-dihydroxyethyl)-3,6-diphenylbicyclo[2.2.0]hexane-1,2,4,5-tetraol serves as a key intermediate in the synthesis of various pharmaceuticals. Its chiral polyol framework provides opportunities for constructing complex carbohydrates and glycosides. Research teams utilize this compound as a starting material for creating antiviral agents and glycosidase inhibitors. The bicyclic structure enhances conformational restriction, making it valuable for creating receptor-targeted molecules. Additionally, it serves as a building block for developing chiral catalysts and organocatalysts for asymmetric synthesis.
