- Thiosemicarbazones of formyl benzoic acids as novel potent inhibitors of estrone sulfatase
-
Thiosemicarbazones of the microbial metabolite madurahydroxylactone, a polysubstituted benzo[a]-naphthacenequinone, have been previously reported by us as potent nonsteroidal inhibitors of the enzyme estrone sulfatase (cyclohexylthiosemicarbazone 1, ICsu

- Regiospecific synthesis of 3-(2,6-dihydroxyphenyl)phthalides: application to the synthesis of isopestacin and cryphonectric acid
-
DBU catalyzed condensation of phthalaldehydic acids and 1,3-diketones has been developed to be a general method for the synthesis of 3-substituted phthalides. This method, in combination with mercuric acetate mediated oxidative aromatization has been util

- Photochemical Transformations of Methoxyphthalaldehydic Esters: Synthesis of Methyl 6-Methoxyphthalaldehydate from the 3-Methoxy-isomer
-
Irradiation of the 3-methoxyphthalaldehydate (4a) in methanol gives an excellent yield of the methoxyphthalide (1c) which can be converted into the 6-methoxyphthalaldehydate (3a) in excellent yield, thus effecting an 'isomerization' of the original phthal
