AN INTRAMOLECULAR CYCLOADDITION-SIGMATROPIC REARRANGEMENT APPROACH TO (+/-) GASCARDIC ACID

A general intramolecular Diels-Alder:anionic oxy-Cope strategy for the synthesis of tricyclic skeletons and its application to the preparation of the gascardic acid precursor 12 is described.In situ generation of the appropriate cyclopentadiene 5 by isomerization (Et3N) afforded the adduct directly or with EtAlCl2 as catalyst.The requisite potassium salt of the 1,5 diene 10 rearranged at 67 deg C to the fused ring ketone 11.Selecvtive allylic oxidation and reduction provided 12.

A New Approach to Hydroazulenes via Olefin Metathesis

Several functionalized diolefins cyclize to hydroazulenes (among others) via olefin metathesis with CH3ReO3.These conversions are regioselective and occur with high diastereoselectivity.

The regioselectivity of the alkylation of alkali metal salts of 2-methyl-cyclopentane-1,3-dione with alkyl halides depends significantly on the structure of the alkylating reagent and the type of solvent used in the reaction.Unsubstituted saturated primar
