SYNTHESYS OF THE C11-C28 SUBUNIT OF THE AVERMECTINS

Construction of the trisubstituted double bond of the C11-C28 subunit of avermectin A1a and B1a has been achieved in a five-step sequence.

Total Synthesis of Ionophore Antibiotic X-14547A

A highly stereocontrolled and convergent total synthesis of optically active ionophore antibiotic X-14547A (1) was designed and carried out.Degradative reactions led to the key intermediates 3 and 6, which served as convenient comparison stages.The tetrah
