Synthesis of benzyl esters using 2-benzyloxy-1-methylpyridinium triflate.
Triethylamine (Et3N) mediates esterification reactions between the title reagent (1) and carboxylic acids. Alcohols, phenols, amides, and other sensitive functionality are not affected; a dual role for Et3N as a promoter and a scavenger is postulated. Benzyl esters are obtained from substrates including amino acid and sugar derivatives.
متن کاملMicrowave-assisted benzyl-transfer reactions of commercially available 2-benzyloxy-1-methylpyridinium triflate.
Benzylation of alcohols and other substrates under thermal conditions translates smoothly from conventional heating into MW-assisted organic synthesis (MAOS). Reactions times are decreased from hours to minutes while good to excellent yields are maintained. MW heating should be considered for benzylation of high-value substrates using the title reagent.

A series of 2-amino-5-(4-(benzyloxy)benzyl)thiophene-3-carboxylic acid derivatives was designed and synthesized. The derivatives were evaluated for antitubercular activity against M. tuberculosis ATCC 27294 using the Microplate Alamar Blue Assay (MABA). Among them, compound 8b exhibited the most potent activity with MIC value of
متن کاملCrystal structure of 1-benzyl-4-(4-chlorophenyl)-2-imino-1,2,5,6,7,8,9,10-octahydrocycloocta[b]pyridine-3-carbonitrile
The title compound, C25H24ClN3, comprises a 2-imino-pyridine ring fused with a cyclo-octane ring, which adopts a twist boat-chair conformation. In the crystal, C-H⋯N inter-actions form R 2 (2)(14) ring motifs and mol-ecules are further connected by weak C-H⋯π inter-actions. The resulting supra-molecular structure is a two-dimensional framework parallel to the ab plane.

In the title compound, C(22)H(18)N(2)O, the phenyl and tolyl rings make dihedral angles of 84.71 (7) and 65.11 (6)°, respectively, with the isatin group. The aromatic rings make a dihedral angle of 60.90 (8)°. The imino C=N double bond, exists in an E conformation. In the crystal, mol-ecules are linked by weak π-π stacking inter-actions [centroid-centroid distance = 3.6598 (13) Å].
