A stereocontrolled synthetic route to the C1C18 subunit of pamamycin-607
摘要:
The C1 C18 subunit 2 of the 16-membered macrodiolide pamamycin-607 has been synthesized stereo selectively using the Ag2CO3-mediated intramolecular iodoetherification for the two cis-2,5-disubstituted tetrahydrofurans, crotylation and cuprate epoxide opening for the hydroxyl and methyl substituents.
