(R)-(2,3,4,5,6-Pentadeuterophenyl)oxirane, 5 was synthesised with an overall yield of 6.3% from benzene-d 6 . Friedel-Crafts acylation of benzene-d 6 with methyl oxalylchloride gave methyl 2-oxo-2-(2,3,4,5,6-pentadeuterophenyl)acetate, I that was chirally reduced (Saccharomyces cerevisiae) to methyl (R)-2-hydroxy-2-(2,3,4,5,6-pentadeuterophenyl)acetate (methyl (R)-d,-mandelic acid), 2. Reduction of
(R)-(2,3,4,5,6-Pentadeuterophenyl)oxirane, 5 由苯-d 6 合成,总产率为6.3%。苯-d 6 与草酰氯甲酯的 Friedel-Crafts 酰化得到 2-oxo-2-(2,3,4,5,6-pentadeuterophenyl) 乙酸甲酯,I 手性还原(酿酒酵母)为甲基 (R)- 2-羟基-2-(2,3,4,5,6-pentadeuterophenyl)acetate (methyl (R)-d,-mandelic acid), 2. 用氢化铝锂还原 2 得到 (R)-(2, 3,4,5,6-pentadeuterophenyl)ethane-1,2-diol, 3. 3 的甲苯磺酰化和随后用氢氧化钾处理辅助环化成 5。
