Bu3P-MEDIATED ACYLATION OF (E)-7-ARYLIDENE-6,7-DIHYDROINDOLIZIN-8(5H)-ONES WITH ACYL CHLORIDES

Abstract
The (Z)-7-(1,2-diaryl-2-oxoethylidene)-6,7-dihydroindolizin-8(5H)-ones were synthesized in the acylation reaction of (E)-7-arylidene-6,7-dihydroindolizin-8(5H)-ones with acyl chlorides in the presence of Bu3P in moderate yields. The structures of all products were characterized thoroughly by NMR, IR, HRMS together with X-ray crystallographic analysis.
Keywords
acyl chlorides; indolizin-8(5H)-ones; tributylphosphine, acylation.
