Peptide-catalyzed regio- and enantioselective reduction of α,β,γ,δ-unsaturated aldehydes

A resin-supported peptide catalyst (see box in the scheme) was used in the title reaction. The inherent regioselectivity was overcome by the peptide catalyst to promote the 1,6-selective reaction prior to 1,4-reduction. High stereoconvergence was also achieved when using a mixture of geometric isomers of the starting aldehydes. Ach=1-amino-1-cyclohexanecarboxylic acid. Copyright

The Use of an Arsorane as Isoprenoid Reagent: Synthesis of 5-Substituted 3-Methyl-2,4-pentadienoic Esters (ABA Ester Analogs)

By using of 3-methoxycarbonyl-2-methyl-2-propenylidenetriphenylarsorane (4) as isoprenoid reagent, 5-substituted 3-methyl-2,4-pentadienoic esters 6A and 6B (ABA ester analogs) were synthesized in 88-98percent yields under mild conditions.
