Th. Altel et al., SYNTHESIS OF CHIRAL MULTIFUNCTIONAL POLYC YCLIC FURANOIDS VIA ANNULATION OF PYRANOSIDES, Journal fur praktische Chemie, Chemiker-Zeitung, 338(4), 1996, pp. 320-326
A new strategy to chiral polyfunctionalized furanoids from 2, 3, 4, 7,
8, 9, 11, 12, 14, 15, 17 and 18 from cis orientated epoxypyranosetrif
lates 1 and 6 and dianions of beta-dicarbonyl compounds 10, 13 and 16
is described. The control of the substituents in the satellite ring th
rough acid catalysis is discussed.
