Abstract

Reaction of 2-chlorocyclopentanone with RMgBr (R = Et, pentyl, Ph) gave 61-75% cyclopentanone I, bromination and dehydrobromination of which gave cyclopentenones II. II (R = pentyl, Ph) were converted to cyclopentanones III in 2 steps.

Key words: MASS SPECTROGRAPHY, INFRARED SPECTROPHOTOMETRY, METHYLDIHYDROJASMONATE, NMR SPECTROMETRY, ADDITION REACTION, ORGANO SILICON COMPOUNDS, CYCLOPENTENONE P, REARRANGEMENT REACTION, CYCLOPENTANONE P, CYCLOPENTANONE P
