Enantioselective Synthesis of (−)-Dysiherbaine

Organic Letters, 2015
Dysiherbaine, a natural product isolated from the Marine sponge Dysidea herbacea, has been shown to be a selective agonist of non-NMDA type glutamate receptors, kainate receptors. An enantioselective synthesis of dysiherbaine is reported. Metathesis of the diene followed by conversion of the resulting alkene to the amino alcohol and addition of the ...

Enantioselective Synthesis of (+)-Isobretonin A

The Journal of Organic Chemistry, 1996
An enantioselective synthesis of (+)-isobretonin A is described. The chiral glycerol moiety was enantioselectively prepared by reduction of an optically active beta-keto sulfoxide. The all-trans trienic part of the molecule was stereoselectively synthesized via reductive elimination of a 1,6-dibenzoate 2,4-diene with sodium amalgam.

Enantioselective Total Synthesis of Cylindramide.

ChemInform, 2005
Key steps in the convergent enantioselective synthesis of the cytotoxic natural product cylindramide are tandem Michael addn./electrophilic trapping reactions, Sonogashira coupling, Julia-Kocienski olefination, and macrocyclization. For example, the Sonogashira coupling of pentalene I with iodoacrylate II followed by Julia-Kocienski olefination with ...

Enantioselective Total Synthesis of (−)‐Terengganensine A

Angewandte Chemie, 2016
AbstractA seven‐step enantioselective total synthesis of (−)‐terengganensine A, a complex heptacyclic monoterpene indole alkaloid, was accomplished. Key steps included: a) Noyori's catalytic enantioselective transfer hydrogenation of the iminium salt to set up the absolute configuration at the C21 position; b) a highly diastereoselective C7 ...

Enantioselective Synthesis of (−)-Dendroprimine and Isomers

Journal of Natural Products, 2004
An enantioselective and diastereoselective synthesis of six 5,7-dimethylindolizidine isomers is described via an intramolecular cyclization that involves an allylsilyl nucleophilic group and an acyliminium ion. The first total synthesis of naturally occurring (-)-dendroprimine has been achieved in five steps.
