Abstract

"PROCESSO PARA A PREPARAçãO DE <244><39>CLOROCETONAS". A presente invenção está relacionada ao processo de preparação de <244><39>clorocetonas, tais como 4-fenil-3-t-butilóxi-carbonilamino-2-ceto-1-clorobutano reagindo certos ésteres ácidos aril amino, por exemplo, éster N-(2-t-butoxicarbonil)-L-fenilalanina-4-nitrofenílico, com um composto ilida de enxofre para formar o composto ceto ilida correspondente que é então tratado com uma fonte de cloreto e um ácido orgânico.
