Published: May 2011

Asymmetric Michael reactions of thiols with enones were catalyzed by a Sc(OTf)(3)-chiral bipyridine complex at room temperature in water without using any organic solvents, to afford the desired sulfides in high yields with high enantioselectivities.

Solitary fibrous tumours (SFTs) are rare soft tissue masses that are often clinically silent until they cause mass effect. A paraneoplastic syndrome manifesting as persistent hypoglycaemia, termed Doege-Potter syndrome (DPS), can be associated with these lesions. Surgical treatment is recommended for the management of these tumours.

The functionalized polycycle with densely contiguous tertiary stereocenters is a formidable challenge in synthesizing the parvistemoline family of Stemona alkaloids. We herein report their catalytic, asymmetric total syntheses in 13-14 steps from commercially available 2-(methoxycarbonyl)-pyrrole, featuring the development and deployment of an Ir/Pd-synergistically-catalyzed allylation of α-non-substituted keto esters with secondary aryl-substituted alcohols, stereodivergently accessible to four stereoisomers. Using chiral Pd-enolate and Ir π-allyl complex under neutral conditions, no epimerization occurs.

We present a comprehensive account on the evolution of a synthetic platform for a subfamily of ent-pimaranes. For the most complex member, norflickinflimiod C, five distinct strategies relying on either cationic or radical polyene cyclizations to construct the requisite tricyclic carbon scaffold were explored. Insights from early and late stage oxidative and reductive dearomatization studies ultimately led to a mild, rhodium-catalyzed arene hydrogenation for the final synthetic route.

Application of β-Keto Acylpyrazoles as 2C Synthons in Asymmetric Cyclizations of -Hydroxychalcones: Stereoselective Construction of -3,4-Dihydrocoumarins.

An asymmetric tandem esterification/Michael addition reaction of β-keto acylpyrazoles with -hydroxychalcones has been established under the catalysis of a bifunctional squaramide-tertiary amine. A wide variety of biorelevant 3,4-dihydrocoumarin derivatives were generally obtained in high yields (up to 93%) with excellent diastereo- and enantioselectivities (>19:1 dr, up to 93% ee) under mild reaction conditions. This reaction represents the successful application of β-keto acylpyrazoles as 2C building blocks in catalytic asymmetric cyclizations.
