Synthesis of bistratamide H using a new fluorous protecting group

摘要

Bistratamide H was expeditiously synthesized using a new fluorous protecting group, 2-(tris(perfluorodecyl)silyl)ethoxycarbonyl (FTeoc) via a preparation of thiazole amino acid by a modified Hantzsch's method. The intermediates of the synthesis were easily isolated by fluorous liquid-liquid extraction. The fluorous protecting group was removed from the precursor of bistratamide H with TBAF and the recovered fluorous fragment, tris(perfluorodecyl)silylfluoride, was reacted with vinyl magnesium chloride to give an intermediate in the synthesis of FTeoc reagent. 2006 Wiley-VCH Verlag GmbH & Co.
