Observations regarding the first step of the Julia-Lythgoe olefin synthesis
Hart, David J.,Wu, Wen-Lian
, p. 5283 - 5286 (2007/10/03)
Using DME as a solvent in the addition of metallated sulfones to aldehydes can increase yields in the first step of the Julia-Lythgoe olefin synthesis. The addition of metallated sulfones to ketones is also discussed.
Intramolecular Acylation of an α-Sulfonyl Anion Generated via Halogen-metal Exchange of an α-Halosulfone Bearing an Unsymmetrical Anhydride
Anderson, M. B.,Lamothe, M.,Fuchs, P. L.
, p. 4457 - 4460 (2007/10/02)
α-Halosulfones are useful for the in situ preparation of α-sulfonyl anions in the presence of acylating agents bearing enolizable protons.Inter- and intramolecular acylations can be effected by halogen-metal exchange at low temperature.
