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.

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 (−)-renieramycin T

Organic & Biomolecular Chemistry, 2016
A nonclassical renieramycin with a similar A-ring to ecteinascidin, (−)-renieramycin T, is synthesized through a convergent approach featuring a regio- and stereoselective condensation of isoquinoline and trisubstituted phenylalaninol partners.

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 (+)-Negamycin

The Journal of Organic Chemistry, 2002
An asymmetric synthesis of the antibiotic (+)-negamycin (1) has been achieved, starting from commercially available (5R,6S)-4-(benzyloxycarbonyl)-5,6-diphenyl-2,3,5,6-tetrahydro-4H-1,4-oxazin-2-one (2). The synthesis involved the stabilized Wittig olefination of the lactone carbonyl group of 2 and subsequent asymmetric hydrogenation to generate the ...
