Total Syntheses of (−)-Fumiquinazolines C, E, and H
摘要:
[GRAPHICS]Total syntheses of the heptacyclic fumiquinazollnes C and H have been accomplished efficiently using FmocNHCH(CH2SePh)CO2H as the precursor for the requisite dehydrofumiquinazoline.

selectively formed the appropriate imidazoindolone stereoisomers. Application of the Ganesan-Mazurkiewicz cyclization completed the syntheses. Efficient 14-step syntheses of (-)-fumiquinazolines C (7) and E (3) and a 15-step synthesis of (-)-fumiquinazoline H (8) using FmocNHCH(CH2SePh)CO2H as a dehydroalanine precursor that spontaneously eliminated benzeneselenol without oxidation under the cyclization
