The microbial transformation of coumarin (1) and 6-methyl coumarin (2) using Colletotrichum capsici gave 2-(3'-hydroxypropyl) phenol (3) and 2-(3'-hydroxypropyl)-4-methyl phenol (4). The phytopathogenic fungi effectively reduced the 2H-pyran-2-one moiety of both parent coumarins to respective alcohols.

The present paper describes the synthesis of two Azo-Schiff base named (2-(((2-aminophenyl)imino)methyl)-6-ethoxy-4-((Z)-phenyldiazenyl) phenol, 2-((Z)-((4-aminobutyl)imino)methyl)-6-ethoxy-4-((Z)-phenyldiazenyl)phenol) by diazotization reaction synthesized (3-Ethoxy-2-hydroxy benzaldehyde) with aniline compound to gave Al- Azo – aldehyde and reacted (O-phenylenediamine or1,4-butanediamine) bas...

A novel Schiff base compound, C(20)H(27)NO(2), was obtained by a condensation of rimantadine and 2-hy-droxy-4-meth-oxy-benzaldehyde. An intra-molecular O-H⋯N hydrogen bond supports the phenol-imine tautomeric form. The adamantane and imino-methyl-4-meth-oxy-phenol units are arranged in a folded conformation [C-N-C-C torsion angle = 110.9 (3)°]. In the crystal, highly hydro-phobic adamantane moi...

Molecular structures of 4-(((4-methoxyphenyl)amino)methyl)-N,N-dimethylaniline and 2-methoxy-5-((phenylamino)methyl)phenol synthesized via Schiff bases reduction route are reported. The compounds consist asymmetric units C16H20N2O (1) C14H15NO2 (2) in orthorhombic monoclinic crystal systems, respectively. Compound 1 intermolecular C11—H11···N2 hydrogen bonding with C11···N21 = 3.463(4) Å. hydro...
