摘要
报道了一种合成手性中间体(3R,5R)-3,4,5-三羟基环己酮的新方法。首次以(-)-莽草酸为起始原料,经苯甲酰化、双键氢化、选择性还原甲酯、羟基碘代、碘代烃消除、双键双羟化、片哪醇断裂等步骤,以44.9%的总收率合成了(3R,5R)-3,4,5-三苯甲酰氧基环己酮,所有化合物的结构经^(1)H NMR、^(13)C NMR、IR及MS等确证。
In this paper,a novel synthesis of(3R,5R)-3,4,5-trihydroxycyclohexanone from(-)-shikimic acid was studied.For the first time,(3R,5R)-3,4,5-triphenyloxycyclohexanone was synthesized from(-)-shikimic acid in 44.9%overall yield via benzoylation,hydrogenation of double bond,selective reduction of methyl ester,substitution of hydroxyl with iodine,elimination of iodide,dihydroxylation of double bond and cleavage of pinacol.The structures of all compounds were characterized by ^(1)H NMR,^(13)C NMR,IR and MS.
