Stereoselective concise total synthesis of leodomycin C and D
from commercially available propylene oxide using Jacobsen’s hydrolytic
kinetic resolution (HKR), base-promoted alkyne zipper reaction,
TPP-promoted enyne ester (ynoate) to diene ester (dienoate) isomerization,
and (R)-(+)-2-methyl-CBS-oxazaborolidine reduction
as key steps is reported.
