Asymmetric Synthesis of Arboduridine

Angewandte Chemie, 2023
AbstractThe first asymmetric total synthesis of the monoterpenoid indole alkaloid arboduridine has been accomplished. The tricyclic A/B/D ring system was constructed by an enantioselective Michael reaction followed by intramolecular nucleophilic addition. Intramolecular α‐amination of a ketone forged the piperidine ring, while a Horner–Wadsworth–Emmons

Asymmetric Synthesis of (−)-Swainsonine

The Journal of Organic Chemistry, 2009
We report a new asymmetric synthetic method for (-)-swainsonine utilizing a chiral oxazoline precursor. The key features in this strategy are the diastereoselective oxazoline formation reaction catalyzed by palladium(0), diasteroselective dihydroxylation, and the stereocontrolled allylation reaction with TiCl(4).

Asymmetric Synthesis of Rugulotrosin A

Organic Letters, 2020
A new approach was developed to construct the tetrahydroxanthone by a Knoevenagel condensation/6π-electronic cyclization/aromatization cascade starting from readily available cyclohexane-1,3-diones and unsaturated aldehydes. This strategy provides a new solution for the preparation of monomeric tetrahydroxanthones bearing different functional groups at

Asymmetric synthesis of (+)-abresoline

Tetrahedron Letters, 2005
Abstract The first asymmetric synthesis of (+)-abresoline has been achieved starting from the ( S )-1-(aryl)homoallylic amine, which was prepared enantioselectively by the method based on allylation of the ( R )-2′-(2-naphthyl)-bearing hydroxyoxime ether.
