The preparation and rhodium catalysed CH insertion reactions of (alkoxysilyl)diazoacetates are reported, leading to the diastereoselective synthesis of 3,4,5-trisubstituted l-oxa-2-silacyclopentanes. Reduction of the pendant ester group followed by oxidative CSi bond cleavage furnishes 1,2,4-triols.
报道了(烷氧基甲硅烷基)重氮乙酸酯的制备和铑催化的CH插入反应,导致3,4,5-三取代的1-氧杂-2-硅环戊烷的非对映选择性合成。酯的侧基还原,然后氧化CSi键断裂,得到1,2,4-三醇。
