产品说明 一般描述 Ethyl 1,3-dithiane-2-carboxylate is an α-keto acid equivalent and bulky equivalent of acetate. It participates in syn-selective aldol reactions. It can be prepared from the reaction of ethyl diethoxyacetate and 1,3-propanedithiol in the presence of BF3/Et2O. Asymmetric oxidation of ethyl 1,3-dithiane-2-carboxylate by Modena protocol has been reported to afford trans bis-sulfoxide in 60% yield. Carbanion from ethyl 1,3-dithiane-2-carboxylate may be employed for the preparation of α-keto esters. 包装 5 mL in glass bottle 基本信息 | 经验(实验)分子式 | C7H12O2S2 | | 分子量 | 192.30 | | Beilstein | 1424352 | | EC 号 | 243-838-4 | | MDL编号 | MFCD00006657 | | PubChem化学物质编号 | 24867377 | | NACRES | NA.22 |
