Substituted 4H-pyrans were obtained in high preparative yields by the reaction of 1,5-diketones with acetic anhydride and boron trifluoride etherate in diethyl ether.It is assumed that the heterocyclization of 1,5-diketones includes a step involving the f
3,5-DI-tert-BUTYL-o-BENZOQUINONE AS A REAGENT FOR OXIDATIVE DEHYDROGENATION OF 9R-sym-NONAHYDRO-10-CHALCOGENOANTHRACENES

3,5-Di-tert-butyl-o-benzoquinone is a convenient reagent for the oxidative dehydrogenation of 9R-sym-nonahydro-10-chalcogenoanthracenes.The good solubility of o-quinone itself and the corresponding pyrocatechol facilitates the isolation of the salts of 10
OXIDATIVE CLEAVAGE OF THE C-C BOND IN PROCESSES INVOLVING THE HETEROAROMATIZATION OF 9R-sym-NONAHYDRO-10-OXA(CHALCOGENA)ANTHRACENES

The reaction of 9-(2-methoxyphenyl)- and 9-(2-thienyl)-sym-nonahydro-10-selena(thia)anthracenes with trifluoroacetic acid causes their heteroaromatization with the elimination of substituents from the γ positions of the heterorings.A similar transformatio
