要旨:
Potassium-graphite laminate (C8K) in oxolane almost instantaneously converts O-alkyl and O-alkylidene pyranosyl and furanosyl chlorides under extremely mild conditions and in high yields into pyranoid and furanoid glycals, which in the presence of an additional mole of C8K, are efficiently O-alkylated or O-silylated in easily conducted one-pot reactions.
