A convergent, two-fragment synthesis of the C10-C25 northern moiety of avermectins has been developed. Along with our previous work in this area, the present contribution represents a formal synthesis of Ivermectin aglycone. Furthermore, according to a strategy leading to non γ-pyranone adducts from the condensation reaction between acetylacetone dianion and convenient aldehydes, 23-hydroxylated C10-C25
