A 8-O-4' neolignan, has been stereoselectively synthesized in eight steps from ferulic acid, and the directly cis opening of epoxide in eposidation and Mitsunobu reaction were used ingeniously as two key steps with high stereoselectively.展开更多
A novel enantioselective synthetic approach to 1,4-benzodioxane lignans was reported in which (2R, 3R)- and (2S, 3S)-2-(4-hydroxyphenyl)-3-hydroxymethyl-1, 4-benzodioxan-6-carbaldehyde were first synthesized.
