Making Mixtures to Solve Structures: Structural Elucidation via Combinatorial Synthesis
摘要:
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.

Alkyliodides can be coupled with α,β-unsaturatedestersusingNi2B(0.05–0.2 eq)-BER(3 eq) in methanol at room temperature. Products (68–95%) are conveniently isolated, simply filtering the resin and evaporating the excess enoates and methanol.
