  Total synthesis of (±)-nitidanin and novel procedures for determination of the location of the side chains on 1,4-benzodioxane

  摘要：

  Regioselective cycloaddition of o-quinone 4 and protected sinapyl alcohol 2 gave 1,4-benzodioxane 5, which was converted to (+/-)-nitidanin (6), an antimalarial compound. Two novel procedures were developed to determine the location of the side chains of the adduct (5) based on partial ring cleavage. (c) 2006 Elsevier Ltd. All rights reserved.

  We have achieved total synthesis of cleomiscosin C (aquillochin) through regioselective cycloaddition of o-quinone and protected sinapyl alcohol as a key step. During preparation of o-quinone from phenol by IBX oxidation, silyl substituents adjacent to the phenolic hydroxyl group afforded effective inhibition of an undesired oxidative elimination.

  A process for synthesizing 1,4-benzodioxin, through oxidation of a phenol to an o-quinone followed by treatment with an enamine, has been developed. Adduct stereochemistry is found to be retained via this one-pot reaction. The method uses hypervalent iodine reagent under mild conditions and is compatible with a wide scope of phenols and enamines.
