Catalyst recycling via hydrogen-bonding-based affinity tags.

[Structure: see text] A novel procedure for catalyst recycling is described. Copper(I)-based catalysts, equipped with an affinity tag, are isolated from crude reaction mixtures on the basis of quadruple hydrogen-bonding interactions using a resin functionalized with complementary affinity tags. Recycled catalysts were successfully used to catalyze a tandem Sonogashira coupling/5-endo-dig cyclization and a Cu-catalyzed [3+2] Huisgen cycloaddition reaction in high yields.

Total synthesis and bioactivity of some naturally occurring pterulones.

The naturally occurring pterulones 1, 3, and 13 were synthesized in high overall yield from readily available methyl 3-(2-propenyl)-4-(2-propenyloxy)benzoate (6) by employing ring-closing metathesis (RCM) as a key step. The biological activities of the synthesized pterulones were tested using cells of Rhodotorulaglutinis and Saccharomyces cerevisiae.
