A series of naphthalenyl-substituted arenediynes were prepared to examine photochemical reactivity. For naphthalen-1-ylethynyl arenediyne, 350 nm photolysis resulted in a tandem [2 + 2] photocycloaddition to afford cyclobutene adducts. For naphthalen-2-ylethynyl derivatives, electron-donating methoxy substituents were found to facilitate C(1)-C(6) Bergman cyclization at 300 nm. Theoretical calc...
The five-membered ring in the the title mol-ecule, C(24)H(25)NO, fused with the phenyl-ene ring, is almost planar (r.m.s. deviation = 0.023 Å), with the methyl-ene C atom deviating most from this mean plane [0.031 (1) Å]. The tertiary N atom shows a flattened pyramidal configuration [Σ(angles at N) = 350.3 (6)°].
Eight 1-[(2-chlorophenyl)carbamoyl]naphthalen-2-yl alkylcarbamates and eight 1-[(2-nitrophenyl)carbamoyl]naphthalen-2-yl alkylcarbamates were tested for their activity related to the inhibition of photosynthetic electron transport (PET) in spinach (Spinacia oleracea L.) chloroplasts. The PET-inhibiting activity of the compounds was relatively low; the corresponding IC50 values ranged from 0.05 ...
As a part of systematic investigation of biologically active compound, new azo dye ligand N-(4, 6-dimethylpyrimidin-2-yl)-4-((2-hydroxynaphthalen-1-yl) diazenyl) benzene sulfonamide has been synthesized by diazotization of 4-amino-N-(4, 6-dimethylpyrimidin-2-yl) benzenesulfonamide and coupled with coupling compound, naphthalen-2-ol. A new series of Ni (II), Cu (II), and Zn (II) complexes derive...
