Alternatives to α-Diazo Ketones for Tandem Cyclization-Cycloaddition and Carbenoid-Alkyne Metathesis Strategies. Novel Cyclic Enol-Ether Formation via Carbonyl Ylide Rearrangement Reactions

Attempts to form carbonyl ylides from free carbenes derived from diazirines or diazo compounds lacking electron-withdrawing substituents resulted in azine formation or Wolff rearrangement, respectively.Iodonium ylides proved to be a possible alternative to α-diazo compounds for metallocarbenoid generation, similar reactivity being observed for both systems.Studies into the rearrangement chemistry of carbonyl ylides provided a novel cyclic enol-ether synthesis via a 1,4-hydrogen shift process.
