Stereocontrolled Synthesis of Polyfunctionalized cis-Decalins from 2-Methoxyphenols: Total Syntheses of (()-Eremopetasidione, (()-3â-Angeloyloxyfuranoeremophilane, and (()-3â-Methacryloyloxyfuranoeremophilane

Enantioselective synthesis of cis-decalins using organocatalysis and sulfonyl Nazarov reagents.

The first organocatalytic synthesis of cis-decalins using sulfonyl Nazarov reagents is reported. The Jørgensen's catalyst directs this highly enantioselective synthesis using different cyclohexenal derivatives.

Novel stereocontrolled syntheses of tashiromine and epitashiromine

A novel stereocontrolled approach has been developed for the syntheses of tashiromine and epitashiromine alkaloids from cyclooctene β-amino acids. The synthetic concept is based on the azetidinone opening of a bicyclic β-lactam, followed by oxidative ring opening through ring C-C double bond and reductive ring-closure reactions of the cis- or trans-cyclooctene β-amino acids.

Tether-controlled cycloadditions for the asymmetric synthesis of decalins: increased selectivity in acetonitrile solvent.

[reaction: see text] The beneficial influence of cis-isopropylidene acetal tether control groups, to facilitate the asymmetric synthesis of substituted decalins by intramolecular Diels-Alder reactions, is described. Compared to trans-acetonides, these cases proceed under milder conditions to afford the cis-fused adducts from an endo transition state. An unusual acetonitrile solvent effect exert...
