Journal ArticleDOI
Phosphine-catalyzed asymmetric synthesis of beta-lactones from arylketoketenes and aromatic aldehydes.
TL;DR: The development of a chiral phosphine-catalyzed formal [2 + 2] cycloaddition of aldehydes and ketoketenes that provides access to a variety of highly substituted beta-lactones is reported.
Journal ArticleDOI
A Facile Phenol-Driven Intramolecular Diastereoselective Thermal/Base-Catalyzed Dipolar [2 + 2] Annulation Reactions: An Easy Access to Complex Bioactive Natural and Unnatural Benzopyran Congeners
TL;DR: The complex bioactive natural and unnatural benzopyran congeners have been synthesized using one-/two-step approaches in very good yields from the reactions of two different dihydroxyphthalides, natural resorcyclic acid derivative, and trihydroxybenzophenone through the phenol-driven intramolecular diastereoselective thermal/base-catalyzed dipolar [2+2] cycloaddition reactions.
Journal ArticleDOI
Recent Developments in Vinylsulfonium and Vinylsulfoxonium Salt Chemistry
TL;DR: This review describes advances in the literature since 2000 in the area of reactions of Vinylsulfonium and vinylsulfoxonium salts, with a particular emphasis on stereoselective examples.
Journal ArticleDOI
Facile synthesis of 1,3,7-trihydroxyxanthone and its regioselective coupling reactions with prenal: simple and efficient access to osajaxanthone and nigrolineaxanthone F.
TL;DR: The regioselective coupling reactions of 1,3,7-trihydroxyxanthone with prenal in the presence of calcium hydroxide at room temperature and under thermal conditions at 140-150 degrees C have been demonstrated to exclusively obtain the natural products osajaxanthone in 75% yield and nigrolineaxanthones F in 98% yield, respectively.
Journal ArticleDOI
Alkaloid-Catalyzed Enantioselective [3 + 2] Cycloaddition of Ketenes and Azomethine Imines
TL;DR: This method represents the first unambiguous example of an enantioselective reaction between ketenes and a 1,3-dipole.
