Studies toward the Total Synthesis of Amphidinolide N: Stereocontrolled Synthesis of the C13–C29 Segment
摘要:
A stereocontrolled synthesis of the C13-C29 segment of amphidinolide N, a marine macrolide natural product that is extremely potent cytotoxic, is described.

AbstractIt is shown that the position of the double bond close to the hydrocarbon end of an aliphatic diene functionalized at C(1) can readily be determined by chemical ionization with NO+. Owing to the low abundance of the ions characteristic for the position of the other double bond, its localization may be difficult. Measurement of the chemical ionization (nitric oxide as reagent gas) spectra of the corresponding epoxides or collision activation studies can help.
