synthetic routes to 3-deoxy- d - manno -octulosonic acid (KDO) and 3-deoxy- d - arabino -2-heptulosonic acid (DAH) from common sugar substrates are reported. Chain homologation of the sugar substrates was accomplished by Wittig olefination and Corey–Fuchs alkynylation. A new cyclization strategy was investigated to access the desired pyranosyl isomer of the KDO target.
