Spin system assignment of homo-o-phenylene ethynylene oligomers.

We previously reported the synthesis and solution characterization of short o-phenylene ethynylene (oPE) foldamers. Proton correlation techniques are not adequate for NMR assignment in these compounds as the ethynylene linkers interrupt proton connectivity. In order to facilitate structural characterization and more fully harness the power of NMR, it is necessary to know the sequence of spin systems along the molecular backbone. For example, spin system assignment is required to unambiguously assign NOE correlations for structural determination of folded forms in solution. Therefore, we developed a method to assign the aromatic spin systems in these compounds using HMBC experiments. This has been performed for tetrameric (Es4), pentameric (Es5), and hexameric (Es6) oligomers and is expected to prove useful for this class of foldamers in general. The proton assignments obtained by this technique have been useful toward confirming the previous hypotheses of helical folding in oPE systems.

Nickel-catalyzed thioallylation of alkynes with allyl phenyl sulfides.

Allylic sulfides add to alkynes in the presence of nickel complexes efficiently to afford thio-1,4-dienes regio- and stereoselectively. Functional groups such as alkoxy, siloxy, hydroxy, carboalkoxy, chloro, and cyano groups are tolerated. A mechanism that involves a pi-allyl nickel intermediate is proposed on the basis of isolation of pi-allyl complexes and distribution of products in the reactions of alpha- or gamma-methylated allyl sulfide. [reaction: see text].
