Abstract

The diazo transfer of the alpha-benzoylated ester utilizing p-acetoamidobenzenesulfonyl azide affords the alpha-diazo ester in good yield. Gram quantities of alpha-diazo esters could be easily prepared with the use of this simplified procedure.

Abstract

The preparation of the enantiomerically pure alkenyl cyclopropanes with the common organic functional groups resulted in the rapid assembly of 2,5-disubstituted cyclohexenone derivatives. The product, 2,5-disubstituted cyclohexones are treated as building blocks for target directed synthesis.

Abstract

The preparation of alkenyl cyclopropanes 1 with a variety of common organic functionalities is reported. These substrates were subjected to the Fe(CO)5-mediated carbonylation process under a CO atmosphere, leading to the formation of 2,5-disubstituted cyclohexenones 2, important intermediates for target-directed synthesis.
