Two chromene carboxylic acids having a fully substituted benzene ring, 8-chlorocannabiorcichromenic acid (1) and mycochromenic acid (2), were synthesized via thermal cyclization of the corresponding four substituted phenyl propargyl ethers.
通过对相应的四个取代的苯基炔丙基醚进行热环化反应,合成了具有完全取代的苯环的两个色烯羧酸,即8-氯大麻二茂铁铬酸(1)和霉菌色素(2)。
