产品说明 一般描述 α-Hydroxy-γ-butyrolactone is a 5-membered cyclic ester. It was obtained via tin-conversion of biomass-derived 1,3-dihydroxyacetone (DHA) and formaldehyde. 应用 α-Hydroxy-γ-butyrolactone may be employed as starting reagent in the synthesis of series of seco-pseudonucleoside synthons via aminolysis. It may be employed as starting reagent in the synthesis of enantiomerically pure orthogonally protected δ-azaproline, via Mitsunobu reaction. 包装 5 g in glass bottle 基本信息 | 经验(实验)分子式 | C4H6O3 | | 分子量 | 102.09 | | Beilstein | 80587 | | MDL编号 | MFCD00134268 | | PubChem化学物质编号 | 24862411 | | NACRES | NA.22 |
