4-(5-(2-Methoxyphenyl)-1,3,4-oxadiazol-2-yl)benzohydrazide (5) was synthesized by three steps. The synthesis started with 2-methoxybenzohydrazide to form hydrazone (3) which was then cyclized to oxadiazole (4) and finally, treatment of oxadiazole (4)...
The reported compound 4 was synthesized and fully characterized by 1H NMR, 13C NMR, 11B NMR, 19F NMR, and high resolution mass spectrometry.
The title compound, 3,5-bis(2-hydroxybenzylidene)piperidin-4-one (3), was prepared via reaction of 2-hydroxybenzaldehyde (1) and 4-piperidone (2) under microwave irradiation in the presence of 10% NaOH solution. The compound was fully characterized f...
The title compound 3-(4-amino-1,2,5-oxadiazol-3-yl)-4-(4-nitro-1,2,5-oxadiazol-3-yl)-1,2,5-oxadiazole (ANFF-1) was synthesized by: (1) by reaction of 3,4-bis(4-nitro-1,2,5-oxadiazol-3-yl)-1,2,5-oxadiazole (BNFF-1) with gaseous ammonia in toluene and...
A novel expedient synthesis of benzo[b]thiophene-2-carbaldehyde 2 is reported. It is based on the one-pot sequential reaction of methylthiobenzene 1 with BuLi and DMF to give 2 in 80% isolated yield.
A natural diastereomeric mixture of 5-(6-hydroxy-2,5,7,8-tetramethyl-chroman-2-yl)-2-methyl-pentanoic acid methyl ester (1), was isolated from the soft coral Sinularia arborea. The structure of 1 was elucidated by spectroscopic methods and 1 displaye...
