Efficient synthesis of ningalin C

(Matrix presented) A concise and efficient synthesis of the permethyl derivative of the marine alkaloid ningalin C (2) has been accomplished. The key step involves the formation of a pyrrolinone fron an aminoquinone in one pot. An efficient route for the

First total synthesis of the marine alkaloids purpurone and ningalin C

Purpurone is obtained from 3-(3,4-dimethoxyphenyl)pyruvic acid, 2-(4-methoxyphenyl)ethylamine and 2',2',2'-trichloroethyl 2-bromo-2-(3,4-dimethoxyphenyl)acetate in seven steps with an overall yield of 11%. Ningalin C is synthesized from 1-[2-(3,4-dimethox
