Summary: A simple and improved protocol for the a-monobromination of acetophenone and acetyl carbazole derivatives using different ammonium hydrotribromide salts under mild reaction condition was described.
3-(2,5-disubstituted-1H-indol-3-yl)-1(4-substituted phenyl) prop-2-en-1-one 2a-i were prepared by reported method [29] by reacting disubstituted indole aldehydes with substituted acetophenone in the presence of piperidine in good yields.
It is also noteworthy that the WK reaction allows for a form of "umpolung" which involves the reversal of polarity, in the sense that, starting from the acetophenone substrate, for example, the carbonyl is reduced while the terminal methyl group is oxidized.
A set of four E-3 arylidene flavanones were synthesized by simple base catalysed condensation of appropriate aryl aldehydes and 2'4'dihydroxy acetophenone. Screened analgesic activity by hot plate method,anti-oxidant activity by spectrophotometric method and anti-bacterial activity by cup-plate method.
Phenylhydrazine hydrochloride was slowly added to the mixture of 4'-substituted acetophenones and acetic acid in ethanol.
Acylhydrazide Schiff bases were synthesized by condensening different acylhyrazides with different aromatic aldehydes and acetophenones by refluxing in ethanol for 2 to 3 hours and reactions were monitored by TLC (Scheme-1).
The solution phase synthesis of 2,3-dihydro-1,5-benzothiazepines 4 and 5 was carried out by heating under reflux of [alpha], [beta]-unsaturated ketones 3 (obtained from reaction of an aldehyde and the acetophenones 2)with o-aminothiophenol in dry acidic MeOH in the presence of drops of glacial C[H.sub.3]COOH.
General procedures for iodination of hydroxy aromatic aldehydes, hydroxy acetophenones, substituted anilines and phenols in ethanol, acetic acid and 2-methoxyethanol:

Aggregation inhibitory activity of minor acetophenones from Paeonia species.
[18] synthesized a large number of chalcones by reacting differentially substituted acetophenones with 2,4-dimethoxybenzaldehyde and 3,4,5-trimethoxybenzaldehydes using Claisen-Schmidt condensation and analyzed their anticancer and anti-inflammatory activities.
