Abstract

The invention discloses a method for synthesizing caulerpin. In the method, the caulerpin is prepared from phenylhydrazine and 3-oxo-1,5-dimethyl glutarate by the following synthesis route. The method comprises the following steps: 1. carrying out Fischer indole reaction on phenylhydrazine 2 and 3-oxo-1,5-dimethyl glutarate 3 by using an acid catalyst to obtain methyl 2-(3'-methoxycarbonyl)indolyl-acetate 4; 2. carrying out Claisen ester condensation on the methyl 2-(3'-methoxycarbonyl)indolyl-acetate 4 by using an alkali catalyst to prepare an intermediate 5; and 3. carrying out catalytic hydrogenation or NaBH4 reduction on the intermediate 5, and dehydrating to obtain the caulerpin 1.Compared with the existing caulerpin synthesis route, the synthesis method disclosed by the invention has the advantage of cheap and accessible raw materials; the reaction conditions are mild, and every step can be performed at normal temperature; and the method is simple and convenient to operate, is easy for mass synthesis, and is applicable to industrial production.

Description

technical field

[0001] The invention relates to a chemical method for synthesizing phycoerythrin. Background technique

[0002] Caulerpin is a secondary metabolite extracted from seaweed, which has a variety of significant biological activities.

[0003]

[0004] (1) The application prospect of phycoerythrin as plant growth hormone

[0005] Studies have shown that phycoerythrin can effectively promote the growth and development of soybean adventitious roots, and the effective concentration is very low. In the future, phycoerythrin may be used as a substitute for auxin and be widely used in agricultural production. (Wu Lunxiu, He Tingyu, Gu Wenxiang, Wang Jinxiang, Phycoerythrin promotes the formation of adventitious roots from soybean cuttings, Plant Physiology Communications, 2010, 46 (9), 895-901.)

[0006] Phycoerythrin has both the properties of a growth promoter and a growth inhibitor similar to ethylene, so it can promote or inhibit growth, delay fruit ripening a...
