Iridoids from carbohydrates via Pauson-Khand reaction: Synthesis of advanced highly oxygenated cyclopentane-annulated pyranosides from D-glucal derivatives

The Pauson-Khand reaction on suitable 4-oxa-hept-1-en-6-ynes (1, 17) obtained from 3,4,6-tri-O-acetyl-D-glucal gives the cyclopentane-annulated pyranosides (2, 18) that can be efficiently and stereoseiectivelly transformed into chiral, advanced, highly oxygenated intermediates (10, 16, 24) for the synthesis of iridoid aglycones.
