Hydrazones are an important class of compounds found in many synthetic products. Due to their importance in synthetic chemistry, the present article reports the synthesis of a new series of ten compounds based on the coupling of 2-oxo-3(2H)-benzothiazoleacetic acid, hydrazide and 2-thioxo-3(2H)- -benzothiazoleacetic acid, hydrazide with different aldehydes. The structures of the synthesized compounds were confirmed by elemental analyses, IR, 1H- -NMR, 13C-NMR and FAB+-MS spectral data. Copyright 2012 (CC) SCS.

Ozonolysis of Olefins VIII [1]. Synthesis of Phenoxyacetaldehydes by Ozonolysis of Allylphenylethers

, p. 167 - 172 (2007/10/03)
A new route for the preparation of a series of phenoxyacetaldehydes (2a-j) which are useful intermediates or products, is described. It starts from the easily available allylphenylethers 1a-j which are ozonized at -40°C and further treated with dimethylsulfide to give solutions of the corresponding phenoxyacetaldehydes 2a-j; these are purified by column chromatography. Reaction of 2a-j with 1-methyl-1-phenylhydrazine leads to the corresponding hydrazones 3a-c, 3e-g, 3i, and 3j. The aldehydes can also be transformed into the stable dimethylcetals 4a, 4e, 4h, and 4i by reaction with trimethyl orthoformate.
