Enones tandem vicinal difunctionalization

In this synthesis, a tandem vicinal difunctionalization of enone 18 provides an exceedingly simple solution to the task of synthesizing spirocyclic intermediate 16. When 18 is treated with the or-ganocuprate reagent, t-Bu2Cu(CN)Li2, a smooth 1,4- or Michael ad-... [Pg.456]

Ketones, specifically 2-alkenones and 2-cycloalkenones, have been used extensively as substrates for tandem vicinal difunctionalization, allowing delineation of various reactivity patterns based upon the structural elements present in the enone. Aldehyde substrates have been used less widely comparison... [Pg.242]
