β¦ Synopsis
A highly stereoselective and efficient synthesis of methynolide, the aglycone of 12membered macrolide methymycin, was achieved from of Cl-C8 and C9-Cl3 segments synthesized from D-glucose by employing some stereoselective reactions and benzyl-type protecting groups.

Segments i (Cll-C17) and ii (Cl-ClO), synthesized from D-glucose by employing some stereoselective reactions and benzyl-type protecting groups, were esterified and cyclized to the 16-membered enone, which was readily converted to tylonolide, the aglycone of tylosin. Tylosin is a typical 16-membered
