THE CHEMISTRY OF NATURAL PRODUCTS

本文介绍了一种合成海洋产品monobromo和dibromphakellin的方法， 生物遗传模式路线。 在一项相关的研究中， 研究麻痹性贝类毒素石房蛤毒素。 米孕酚A厂 不属于类固醇的雌激素正在合成。 麦角酸 一些相关化合物是多种药物的结构单元。 一 麦角酸和相关麦角林的生物遗传模式合成 正在开发中。 人们正试图将双萘醌 涉及含有以下基本环结构的分子内羟醛产物： 萘环素类抗生素 一个关于生物起源的推测性方案 thiaspirane生物碱正在实验测试中。 一个新 将合成由寄生曲霉产生的抗生素。

The marine products monobromo and dibromphakellin will be synthesized by a biogenetically patterned route. In a related study a synthesis of the paralytic shellfish poison saxitoxin is investigated. Mirestrol a plant estrogen not belonging to the steriods is being synthesized. Lysergic acid and some related compounds are structural units of several drugs. A biogenetically patterned synthesis of lysergic acid and related ergolines is being developed. Attempts are being made to convert bisnaphthoquinones to intramolecular aldol products containing the basic ring structures of the naphthocyclinone antibiotics. A speculative scheme for the biogenesis of the thiaspirane alkaloids is being tested experimentally. A new antibiotic produced by Aspergillus parasiticus will be synthesized.
