Abstract

Résumé/Abstract Chemical conversion of lapachol to α-lapachone, β-lapachone, dehydro-a- lapachone, dehydroiso-α-lapachone and dehydroiso-β-lapachone by reaction with aqueous NaNO 2 and glacial AcOH; rhinacanthin-A, stenocarpoquinone-A, stenocarpoquinone-B and its isomer by reaction with meta-chloroperbenzoic acid at 0 for 30 min and dehydro-α- lapachone and dehydro-β-lapachone at 25 for 4 h respectively and di-and tribromo ...
