Although nitrocyclopropanedicarboxylic acid esters are widely used in organic syntheses, nitrocyclopropanes with an acyl group have not yet been synthesized. When adducts of β-nitrostyrene and 1,3-dicarbonyl compounds are treated with (diacetoxyiodo

A systematic study of the Diels–Alder reaction of α-nitrocinnamate was performed. The reaction of p-substituted α-nitrocinnamate with 2,3-dimethyl-1,3-butadienes smoothly proceeded regardless of the p-substituent, which was either an electron-don

2-Aza-9-fluorenone derivatives were synthesized and their optical properties were investigated. The UV–visible absrption spectra revealed λmax values in the range of 350–380 nm, with a shift to the longer wavelength when an electron-donating gro

A systematic study on the distortion of a naphthalene ring was performed using steric repulsion between peri-substituents at the 1- and 8-positions. The introduction of bromo groups into the methyl groups of the 1,8-dimethylnaphthalene enhanced the s

Many biologically active nicotinonitriles have been reported to date. Consequently, the development of synthetic methods for multiply arylated/alkylated nicotinonitriles remains a sought-after field of research. In the present work, a new synthetic s
