Paragraph 0045; 0050, (2018/09/21)
The invention belongs to the field of organic chemical synthesis, and discloses a simple synthesis method of caulerpin. The method includes the steps of firstly, using indole as the raw material without protecting amidogen on the indole, and conducting affinity substitution of methyl acetate on a second site of the indole to generate indole-2-methyl acetate; secondly, conducting a formylation reaction on a third site of the indole-2-methyl acetate to obtain 3-formyl-2-indole methyl acetate; finally, conducting between-two-molecule cyclization on the 3-formyl-2-indole methyl acetate to obtain the caulerpin. Compared with the prior art, the method is simple in process, low in raw material cost, mild in reaction condition, beneficial for industrialization, quite high in medical value and widein market prospect, and the synthesis cycle is greatly shortened.
