2-Benzyloxy-1-naphthaldehyde
In the title compound, C(18)H(14)O(2), the dihedral angle between the phenyl and naphthyl ring systems is 21.8 (3)°. The packing of mol-ecules in the crystal structure is stabilized by weak inter-molecular C-H⋯O hydrogen bonds.
متن کامل2-hydroxy-1-naphthaldehyde 2-methylthiosemicarbazone.
Ligands of the aroylhydrazone class have shown much promise as potential chelators for treatment of iron overload disease and perhaps cancer (Johnson et al., 1982; Baker et al., 1992; Richardson et al., 1995; Richardson & Milnes, 1997). Our previous investigations have demonstrated that 2-hydroxy-1naphthaldehyde isonicotinoyl hydrazone, (II), and several other aroylhydrazone chelators possess a...
متن کاملReaction of alpha-ene-vinylcyclopropanes: type II intramolecular [5+2] cycloaddition or [3+2] cycloaddition?
Exposure of alpha-ene-VCPs to catalytic [Rh(dppm)]SbF(6) led to the discovery of a novel Rh(I)-catalyzed [3+2] reaction, which was shown to be efficient for the construction of 5/6- and 5/7-bicyclic compounds rather than the anticipated type II [5+2] products.
متن کاملA DFT-based comparative study on the excited states intramolecular proton transfer in 1-hydroxy-2-naphthaldehyde and 2-hydroxy-3-naphthaldehyde
Potential energy (PE) curves for the intramolecular proton transfer in the ground (GSIPT) and excited (ESIPT) states of 1-hydroxy-2naphthaldehyde (1H2NA) and 2-hydroxy-3-naphthaldehyde (2H3NA) were studied using DFT/B3LYP(6-31G) and TD-DFT/ B3LYP(6-31G) level of theory, respectively. Our calculations suggest the non-viability of ground state intramolecular proton transfer for both the compounds...
متن کاملRhodium-catalyzed [2+2+2] cycloaddition of oximes and diynes to give pyridines.
Oximes and diynes undergo efficient cycloaddition in the presence of a catalytic amount of a cationic rhodium(I)/dppf complex (see scheme). Spontaneous dehydration of the initially formed cycloadducts leads to the formation of a variety of substituted pyridines in moderate to good yields. The transformation could also be achieved in a one-pot procedure using aldehydes.
