Total synthesis of gelsemoxonine [PDF]

open access: yesPure and Applied Chemistry, 2011
The first total synthesis of gelsemoxonine has been accomplished. A divinylcyclopropane–cycloheptadiene rearrangement of the highly functionalized substrate successfully assembled the spiro-quaternary carbon center connected to the bicyclic seven-membered core structure.

Collective Total Synthesis of PPAPs: Total Synthesis of Clusianone via Intramolecular Cyclopropanation

open access: yesNatural Product Communications, 2013
The total synthesis of clusianone was accomplished through the stereoselective construction of a bicyclo[3.3.1]nonane derivative via a three-step sequence which has been utilized for the total syntheses of nemorosone garsubellin A and hyperforin ...

Total Synthesis of (+)-Superstolide A [PDF]

open access: yesThe Journal of Organic Chemistry, 2008
A convergent and highly stereocontrolled total synthesis of the cytotoxic macrolide (+)-superstolide A is described. Key features of this synthesis include the use of bimetallic linchpin 36b for uniting the C(1)-C(15) (43) and the C(20)-C(27) (38) fragments of the natural product, a late-stage Suzuki macrocyclization of 49, and a highly ...

Total Synthesis of (−)-Tuberostemonine [PDF]

open access: yesJournal of the American Chemical Society, 2002
The first total synthesis of the complex pentacyclic Stemona alkaloid tuberostemonine was accomplished in 24 steps and in 1.4% overall yield from a hydroindole intermediate which is readily obtained in three steps from Cbz-l-tyrosine. An innovative synthetic strategy was applied that relays the single stereocenter of the amino acid precursor into nine ...

Development of an Advanced Synthetic Route to Macrosphelides and Its Application to the Discovery of a More Potent Macrosphelide Derivative

open access: yesMolecules, 2014
The discovery of a more cytotoxic macrosphelide derivative, including its total synthesis and bioassay are described. Application of the Koide protocol to a readily available propagylic alcohol allowed the rapid and practical synthesis of a macrosphelide
