Synthesis of the octahydroindole unit of aeruginosins via asymmetric hydrogenation of the Diels-Alder adducts of 2-amido-2,4-pentadienoate
Hoshina, Yoichiro,Doi, Takayuki,Takahashi, Takashi
, p. 12740 - 12746 (2008/03/17)
An optically active octahydroindole, the core unit of aeruginosins (Choi) was synthesized. The Diels-Alder reaction of Danishefsky's diene with methyl (Z)-2-acetamido-2,4-pentadienoates provided the adducts regioselectively in good yield. The adducts were

A short and efficient total synthesis of isoroquefortine C, the 3,12-(Z)-isomer of roquefortine C, from L-tryptophan methyl ester hydrochloride and 4(5)-(hydroxy)methylimidazole hydrochloride is described.
Synthesis of non-natural O-glycosylamino acids derived from n-pentenyl glycosides; model studies and proof of principle for glycopeptide synthesis
Allen, Jennifer R.,Danishefsky, Samuel J.
, p. 736 - 744 (2007/10/03)
Model studies on the transformation of the olefinic unit contained in n-pentenyl glycosides (NPGs) to glycoamino acids is described. The methodology involves a Horner-Emmons olefination with a protected glycine derived phosphonate, followed by asymmetric
Studies towards the synthesis of diazonamide A. Synthesis of the indole bis-oxazole fragment
Bagley,Hind,Moody
, p. 6897 - 6900 (2007/10/03)
The indole bis-oxazole 2, a potential intermediate for the synthesis of the marine natural product diazonamide A 1, has been synthesised, and attempts to construct the model macrocycle (ring B) 3 are also described; in both approaches rhodium carbenoid N-H insertion reactions are used in key steps.
