Reaction of (R)-5-(benzyloxymethyl)tetrahydro-2-furanthione (2), prepared from the corresponding furanone 1, with the diazocarbonyl compounds 3a-c in the presence of rhodium(II) acetate afforded the 2-(acylmethylene)tetrahydrofuran derivatives 4a-c in good yields.
在乙酸铑(II)存在下,由相应的呋喃酮 1 制备的 (R)-5-(benzyloxymethyl)tetrahydro-2-furanthione (2)与重氮羰基化合物 3a-c 反应,得到 2-(酰亚甲基)四氢呋喃衍生物 4a-c,产率良好。
