BCl3 as the sole boron source, the boryl group and thiol group are added to the C-C double bonds simultaneously. After hydrolysis, the corresponding ((tetrahydrothiophen-2-yl)methyl)boronic acid, ((tetrahydro-2H-thiopyran-2-yl)methyl)boronic acid, ((2,3-dihydrobenzo[b]thiophen-2-yl)methyl)boronic acid and (thiomorpholin-2-ylmethyl)boronic acid are obtained with good yield. The boronic acids obtained
已开发出未官能化烯烃的直接且无催化剂的环烷基硫代硼酸酯化反应。在BCl3作为唯一硼源的情况下,将硼烷基和硫醇基同时加到CC双键上。水解后,得到相应的((四氢噻吩-2-基)甲基)硼酸,((四氢-2H-硫代吡喃-2-基)甲基)硼酸,((2,3-二氢苯并[b]噻吩-2-基以良好的产率获得了(甲基)硼酸和(硫代吗啉-2-基甲基)硼酸。可以保护所获得的硼酸以形成合成普遍存在的频哪醇硼酸酯。
