- Acylammonium Salts as Dienophiles in Diels-Alder-Lactonization Organocascades.
- Abbasov ME, Hudson BM, Tantillo DJ, Romo D.Abstractα,β-Unsaturated acylammonium salts, generated in situ from commodity acid chlorides and a chiral isothiourea organocatalyst, comprise a new and versatile family of chiral dienophiles for the venerable Diels-Alder cycloaddition. Their reactivity is unveiled through a highly diastereo- and enantioselective Diels-Alder-lactonization organocascade that generates cis- and trans-fused bicyclic γ- and δ-lactones bearing up to four contiguous stereocen-ters. Moreover, the first examples of Diels-Alder-initiated, stereodivergent, organocascades are described delivering complex scaffolds found in bioactive compounds. The ori-gins of stereoselectivity are rationalized through computa-tional studies. In addition, the utility of this methodology is demonstrated through a concise approach to the core struc-ture of glaciolide and formal syntheses of fraxinellone, trisporic acids and trisporols.

- A Unified Stereodivergent Strategy for Prostaglandin and Isoprostanoid Synthesis.
- Valli M1, Chiesa F, Gandini A, Porta A, Vidari G, Zanoni G.Author information 1Department of Chemistry, University of Pavia , Viale Taramelli, 10, 27100 Pavia, Italy.AbstractAcetoxyfulvene surrended to asymmetric Diels-Alder cycloaddition, paving the way to the development of a unified strategy for the stereodivergent synthesis of both prostaglandins and isoprostanoids. In fact, the cycloadduct was subsequently converted to a common intermediate, which through two different stereoselective pathways afforded the two lactones 1 and 2, which are key building blocks in the synthesis of prostaglandins and isoprostanoids, respectively.

- Highly Stereoselective Generation of Complex Oxy-Bicyclic Scaffolds via an Atom-Economic Pd(II)-Catalyzed Hydroalkynylation, Isomerization and Diels-Alder Cycloaddition Sequence.
- Shen R1, Chen K, Deng Q, Yang J, Zhang L.Author information 1State Key Laboratory of Materials-Oriented Chemical Engineering, College of Chemistry and Chemical Engineering, Nanjing Tech University , Nanjing 210009, P. R. China.AbstractAn atom-economic tandem Pd(II)-catalyzed hydroalkynylation, alkyne-allene isomerization, and Diels-Alder cycloaddition is reported. The reaction employs readily available starting substrates, proceeds in a highly ordered fashion, features high regio- and stereoselectivity, and tolerates a wide range of functionality and structural motifs, thus offering an attractive strategy for producing new molecular complexity and diversity from easily available starting materials. A mechanistic study with density functional theoretical calculations was conducted to rationalize the observed stereoselectivity.
