Azumamide E, a cyclotetrapeptide isolated from the sponge Mycale izuensis, is the most powerful carboxylic acid containing natural histone deacetylase (HDAC) inhibitor known to date. In this paper, we describe design and synthesis of two stereochemical va
A Baylis-Hillman approach to the synthesis of C1-C11 fragment of caribenolide I
Seck, Matar,Franck, Xavier,Seon-Meniel, Blandine,Hocquemiller, Reynald,Figadère, Bruno
, p. 4175 - 4180 (2007/10/03)
Stereoselective synthesis of C1-C11 fragment of caribenolide I, a potent antitumour macrolide isolated from a marine dinoflagellate Amphidinium sp. is described. The key steps rely on asymmetric aldol reactions, to control the absolu

, p. 7557 - 7560 (2008/01/27)
A zoom in on azumamides (2): An efficient synthetic route for two of the newly discovered marine natural products, namely azumamides A and E, has been developed (see picture). The present synthesis was followed by determination of the stereochemical structure of the azumamides. (Chemical Equation Presented)

Mycalolide analog 4, consisting only of the side chain of mycalolide B (2), a trisoxazole macrolide of marine origin, was stereoselectively synthesized using Roush crotylboration, an Evans aldol reaction, and a Paterson aldol reaction as key steps. The an
Short synthesis of the 6,6-spiroketal cores of spirofungins A and B
Dias, Luiz C.,De Oliveira, Luciana G.
, p. 2587 - 2590 (2007/10/03)
(Matrix Presented) Initial efforts toward the total synthesis of the antifungal antibiotics spirofungins A and B are reported. A short and efficient synthesis of the C9-C20 6,6-spiroketal fragments of both compounds is described. This asymmetric approach
Enantio- and stereocontrolled formation of the bisspiroacetal core of spirolide B

, p. 7855 - 7858 (2007/10/03)
The bisspiroacetal core of spirolide B, a marine natural toxin, was synthesized from triketone 10 via one-step bisspiroacetalization, methylation, and silylation accompanied by isomerization of the C-15 spirocenter. The equilibrium of two isomers under ac

, p. 3533 - 3536 (2007/10/03)
(Chemical Equation Presented) The first enantioselective synthesis of the polyketide antibiotics basiliskamides A and B, which exhibit potent in vivo activity against Candida albicans and Aspergillus fumigatus, has been achieved. Serial asymmetric crotylsilane and crotylboronate additions established the C7-C10 stereochemical tetrad. Takai iodoolefination and palladium-mediated cross-coupling were used to install the (Z,E)-vinyl acrylamide. Spectroscopic data is consistent with the assignment of the absolute configurations of the natural products as (7S,8S,9R,10S).

, p. 5383 - 5386 (2007/10/03)
Mycalolide analog 4, consisting only of the side chain of mycalolide B (2), was stereoselectively synthesized and was found to have strong actin-depolymerizing activity.

Chattopadhyay, Shital K.,Pattenden, Gerald
, p. 2429 - 2454 (2007/10/03)
A total synthesis of ulapualide A (1), whose relative stereochemistry was assigned on the basis of an earlier molecular mechanics study of its hypothetical metal chelated complex 9, is described. The synthesis is based on: i, elaboration of the double fun
