Synthesis of fully functionalized intermediates for the bottom half of the 4-acetoxymethyl milbemycin antibiotics (1)

Three fully functionalized bottom half synthons for the preparation of the 4-acyloxymethyl milbemycin antibiotics, e.g., milbemycins α9, α10, and F have been synthesized in only seven steps and reasonable overall yield by an application of our general app
