Regioselective reactions of phenacyl bromide with active methylene compounds

The reactivity of phenacyl bromide with active methylene compounds in the presence of alcoholic KOH, BTEAC (PTC), NaOEt and K2CO3 has been studied.

3,3-Disubstituted 1,5-diaryl-1,5-pentanediones as versatile intermediates for spiro heterocycles

The spiro heterocycles, spiro-4H-pyran pyrazolidinedione/isoxazolidinedione/pyrimidinetrione/thioxopyrimidinedione and spiro-4H-pyran aminopyrazolidinone/isoxazolidinone/hydroxypyrimidinone/mercaptopyrimidinone have been prepared from 3,3-disubstituted 1,5-diaryl-1,5-pentanedione. All the compounds have been characterised by spectral parameters.
