摘要

The regioisomers of the trans-dihydrodiol monomethyl ethers (DME) at the K-regions of 4- and 7-methyl-and 7, 12-dimethylbenz [aIanthracene, which possess a ring methyl substituent peri to the methoxyl group, react with BFretherate to form a single phenol and two regioisomeric phenol methyl ethers, one of which arises by migration of the methoxyl group. In contrast, for DME of benz [a]-anthracene and its 1-, 4-, 7-, 11-and 12-methyl-and ...
