Synthesis of the C9-C21 Fragment of Geldanamycin via a Diastereoselective Substrate-Controlled Hydrogenation
Publication History
Publication Date:
12 November 2008 (online)
Abstract
An Ir-catalyzed diastereoselective hydrogenation was employed to establish the stereogenic center at carbon atom C14 of a C9-C21 fragment of geldanamycin. The fragment was stereoselectively synthesized from d-mannitol in 18 steps.
Key words
ansamycins - diastereoselectivity - hydrogenation - protecting groups - quinones - stereoselective synthesis
