Methanol can be employed as a green and sustainable methylating agent to form C-C and C-N bonds via borrowing hydrogen (BH) methodology. Herein we explored the activity of the acridine-derived SNS-Ru pincer for the activation of methanol to apply it as a C1 building block in different reactions. Our catalytic system shows great success toward the β-C(sp3)-methylation reaction of 2-phenylethanols to provide good to excellent yields of the methylated products. We investigated the mechanistic details, kinetic progress, and temperature-dependent product distribution, which revealed the slow and steady generation of in situ formed aldehyde, is the key factor to get the higher yield of the β-methylated product. To establish the environmental benefit of this reaction, green chemistry metrics are calculated. Furthermore, dimerization of 2-naphthol via methylene linkage and formation of N-methylation of amine are also described in this study, which offers a wide range of substrate scope with a good to excellent yield.

A series of indazole N-oxide derivatives have been synthesized and their antichagasic and leishmanocidal properties studied. 3-Cyano-2-(4-iodophenyl)-2H-indazole N1-oxide exhibited interesting antichagasic activity on the two parasitic strains

A synthetic method was developed for hard-to-get biologically active 2-amino-5-chlorobenzhydrylureas based on reaction of the corresponding benzhydrols with urea in sulfuric acid. The 2-amino-5-chlorobenzhydrylureas were shown to easily undergo on heating cyclization to 1-R-1,2,3,4-tetrahydro-4-phenyl-chloroquinazolin-2-ones.

Process for the production of o-(N-monosubstituted amino)benzyl alcohols which comprises reacting an N-mono-substituted aniline optionally having one or more substituents with a boron trihalogenide at a temperature from about 0° C. to about 100° C. and reacting the resultant boron compound with an aldehyde in the presence of a base at a temperature from about -30° C. to about 100° C. to regiospecifically introduce a 1-hydroxy-alkyl or 1-hydroxy-substituted alkyl group into the ortho position of said aniline.
