Abstract
The dianion (2) of 2, 4-pentanedione and the trianion (10) of 2, 4, 6-heptanetrione were acylated by lithium salts of the unprotected hydroxybenzoates methyl 2-hydroxy-4-methoxy- 6-methylbenzoate(lb), methyl 2, 6-dihydroxy-4-methoxybenzoate (7b), and methyl 2, 4- dimethoxy-6-hydroxybenzoate (7c), as well as by the alkoxybenzoates methyl 2, 4, 6- trimethoxybenzoate (7d) and methyl 2, 4, 64ribenzoxybenzoate (7e). The aryl 1, 3, 5, 7- ...
