Total Synthesis of (+)-Milbemycin β3

The total synthesis of (+)-milbemycin β3 has been achieved in two ways beginning from the appropriate spiroacetal moiety.In the first, coupling of a vinyl-lithium derivative (18) with the spiroacetal aldehyde (19), available from Swern oxidatio

A FORMAL SYNTHESIS OF (+)MILBEMYCIN β3: A WITTIG APPROACH

A new route has been established to generate the C14-C15 trisubstituted double bond of milbemycin β3 by reaction of a Wittig reagent with the appropriate spiroacetal aldehyde.The product of this reaction, after conversion to the iodide and enan
