Making mixtures to solve structures: structural elucidation via combinatorial synthesis

A domino Horner-Wadsworth-Emmons olefination strategy has been used to prepare homologous series of (polyen)ones, and through combinatorial elaboration, corresponding families of highly branched hydrocarbons. Gas chromatography-mass spectrometry of the mixtures has enabled the rapid and unambiguous identification of several highly branched alkanes of geochemical importance. This is the first example of the use of combinatorial synthesis for the elucidation of structural connectivity.

Synthese de cetones a partir de N-phenyl imidothioesters et par l'intermediaire de cetenimines

The thermal decomposition of metallated N-phenyl imidothioesters (lithium or magnesium alkylthio-enaminates generated by either deprotonation or 1,4-addition) led to ketenimines which were trapped in situ by organo-lithium or magnesium compounds to give metallated imines, readily hydrolysed into ketones.This sequence allowed the use of imidothioesters as acyl cation equivalents and also successive and regioselective > 1,3-additions of two different organometallics to an α-unsaturated imidothioester.Ar-turmerone, 2,6-dimethyl-2,7-octadien-4-one, iso-artemisia ketone, α-atlantone and other unsymmetrical ketones were synthesized by this procedure.

Conjugate Addition Reactions of α,β-Unsaturated Ketones with Higher Order, Mixed Organocuprate Reagents, R2Cu(CN)Li2

Conjugate reactions of mixed cuprates R2Cu(CN)Li2 with α,β-unsaturated ketones are reported.These reagents, in most cases, react extremely rapidly affording the corresponding alkylated ketones in high yields.Attempts at trapping the intermediate enolates appeared to be successful using MeI as electrophile; however, the method is not general and was, therefore, not pursued.The effects of solvent and ligand composition on R2Cu(CN)Li2 as well as on the more highly mixed species RTRRCu(CN)Li2 have been examined.The selectivity of ligand transfer in these latter,second generation organocuprates is also discussed.
