A conjugate of fullerene C60 with methyl 3-oxo-3-(2,4,6-trimethoxyphenyl)propanoate (monoacylation product of 1,3,5-trimethoxybenzene with methyl 3-chloro-3-oxopropanoate) has been synthesized under the Bingel-Hirsch conditions. Redox propertie
Operationally Simple and Selective One-Pot Synthesis of Hydroxyphenones: A Facile Access to SNARF Dyes

High selectivity is observed during a Friedel-Crafts acylation/demethylation cascade. In contrast to this cascade, oxygen-containing acylating reagents do not undergo the demethylation step. By the methodology elaborated here, an access is provided to important intermediates for the total synthesis of seminaphthorhodafluor (SNARF) dyes.

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 (1b), 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 2,4,6-tribenzoxybenzoate (7e).The aryl 1,3,5,7-octanetetraones (11b-d and 12) resulting from acylation of 10 were cyclized in biomimetic processes to naturally occurring benzophenones and xanthones.Hydrogenolysis of 1-(2,4,6-tribenzoxyphenyl)-1,3,5,7-octanetetraone (11e) and cyclization gave norlichexanthone (20).
