Paragraph 0033; 0039; 0041, (2016/11/09)
The invention relates to a 2-methoxy-estradiol analogue and a preparation method and application thereof, aiming to solve the problem of preparation of the 2-methoxy-estradiol analogue and realize the application of the 2-methoxy-estradiol analogue to preparation of anti-tumor medicaments. The method comprises the following steps: dissolving 2-methoxy-3-benzyloxy-estradiol-1,3,5-(10)-triene-17beta-alcohol or 17beta-amine serving as a raw material into an organic solvent; in the presence of Lewis alkali, carrying out an acylation reaction on the raw materials and a compound (1) to obtain a 2-methoxy-3-benzyloxy-estradiol-1,3,5-(10)-triene-17beta-ester or 17beta-amide compound (2); carrying out a catalytic hydrogenation to obtain a compound (3); carrying out an acylation reaction or a hydrocarbylation reaction to obtain a compound, namely, the 2-methoxy-estradiol analogue (4), wherein a reaction formula is shown in the specifications. The preparation method of the 2-methoxy-estradiol analogue has the advantages of easiness, mild conditions and high yield, and can be effectively applied to development of anti-tumor medicaments.
