Lucchi, Ottorino De,Marchioro, Carla,Valle, Giovanni,Modena, Giorgio
, p. 878 - 880 (1985)
The Diels-Alder cycloaddition of activated vinyl sulphoxides (1), that are readily obtained by a self-induced chiral oxidation, proceeds highly diastereoselectively to form the corresponding cycloadducts (4) that can be converted into 2-substituted norbor
Self-Induced Diastereoselective Oxidation of Vinyl Sulfides Bearing a Chiral Hydroxy Group as a Way of Preparation of Optically Active Sulfinyl Dienophiles and Their Use in the Asymmetric Diels-Alder Reaction to Cyclopentadiene

, p. 1457 - 1466 (2007/10/02)
Dienophiles 4,5,4' and 5' add with excellent diastereoselectivity to cyclopentadiene as a result of the fact that they assembled most features that are known to govern facial selectivity.Their synthesis entails stereoselective Michael addition of hydroxyt
CHIRAL 1,3-OXATHIANES VIA STEREOSELECTIVE ADDITION-CYCLIZATION OF HYDROXYTHIOLS TO ELECTRON-POOR ACETYLENES
Lucchi, Ottorino De,Lucchini, Vittorio,Marchioro, Carla,Modena, Giorgio
, p. 4539 - 4542 (2007/10/02)
A novel preparation of chiral 1,3-oxathianes via nucleophilic addition of hydroxythiols to electron-poor acetylenes, followed by iodine catalyzed photoinduced cyclization is reported.The stereochemical outcome of the reaction is determined with a conforma
