The C(4-14) polyolic segment of antifungal macrolide strevertenes has been synthesized for the first time in protected form, incorporating four stereogenic centers. The synthetic strategy developed is based on the connection of two subunits prepared start

The aldolisation reaction of lithium ester enolates with chiral α,β-epoxyaldehydes 2a-2f has been investigated. The reaction proceeds with diastereofacial preference in favour of the anti isomer (anti: syn ≈ 4:1) and can be greatly enhanced in the case of

The stereochemistry of addition of lithium enolates to the α,β-epoxyaldehydes 1z-3 has been investigated. Moderate to high diastereoselectivity (up to 13:1) is obtained in favour of the anti isomer, which is explained by the Felkin-Anh model for asymmetric induction.
