Oxidative dearomatization of resorcinol derivatives: useful conditions leading to valuable cyclohexa-2,5-dienones
摘要:
The oxidative dearomatization of resorcinol derivatives with various oxidants is examined, as is the reactivity of cyclohexa-2,5-dienone that emerged. The results of these studies are presented herein. (C) 2003 Published by Elsevier Science Ltd.

amide of dimethylhydrazine for opening and cleavage of a [1,4]-dioxan-2-one is also described. This procedure unmasks the hydroxy dione 36 by jettisoning the chiral directing group. Regioselective O-carbamylation of the 1,3-dione 36 enables the transformation of the remaining carbonyl into the alpha-hydroxy carboxylicacid found in 2. The total synthesis of (+)-rishirilide B (2) requires 15 pots from
