Regiospecificallysubstituted 1-methyl- and 2-methylnaphthalenes, 5-methyl- and 6-methyl-1,2,3,4-tetrahydroanthracenes have been synthesized in good yields through 1,2- addition of the corresponding α-lithio-o-or m-xylenes onto α-oxoketenedithioacetals or their dihydro derivatives followed by cyclodehydration of the resulting carbinols in the presence of borontrifluoride etherate.
