RS)-Naphthotocopherol and its optically active short-chain analog were synthesized by the condensation of menadiol acetate with (3 RS,7 RS,11 RS)-isophytol and (3 RS,4 S)-3,4,8-trimethylnon-1-en-3-ol (ee ∼50%) in the presence of aluminosilicate Zeocar-10. Using (+)-camphor-10-sulfonic acid as a catalyst, naphthotocopherol analogs with the unsaturated isoprenoid side chain were obtained from (3 RS)-linalool or (3 RS
摘要 通过乙酸甲萘酚与(3 RS,7 RS,11 RS)-异植醇和(3 RS,4 S)缩合合成(2RS,4' RS,8' RS)-萘酚及其旋光短链类似物。 )-3,4,8-trimethylnon-1-en-3-ol (ee ∼50%) 在硅铝酸盐 Zeocar-10 的存在下。使用(+)-樟脑-10-磺酸作为催化剂,从(3 RS)-芳樟醇或(3 RS,4 S)-3,4,8-trimethylnona-1中获得具有不饱和类异戊二烯侧链的萘酚类似物,7-dien-3-ol。这些化合物的臭氧分解产生相应的ω-甲酰基衍生物。
