In the presence of catalytic amounts of [1,2-benzenediolato(2-)-O,O′]oxotitanium and trimethylsilyl triflate, 1-O-trimethylsilyl-2,3,5-tri-O-benzyl-D-arabinofuranose stereoselectively reacts with various trimethylsilyl ethers to afford the corresponding 1,2-cis-arabinofuranosides in high yields.
在催化量的[1,2-苯二酚(2-)-O,O']氧钛和三氟甲磺酸三甲基硅酯存在下,立体选择性地生成1-O-三甲基硅基-2,3,5-三-O-苄基-D-阿拉伯呋喃糖与各种三甲基甲硅烷基醚反应,以高产率得到相应的 1,2-顺式-阿拉伯呋喃糖苷。
