Muramatsu, Wataru published the artcilePerfectly Regioselective and Sequential Protection of Glucopyranosides, SDS of cas: 85618-21-9, the publication is European Journal of Organic Chemistry (2010), 827-831, S827/1-S827/67, database is CAplus.
A perfectly regioselective and sequential method for the preparation of orthogonally protected glucopyranosides has been developed. An acyl group was introduced at C(4)-OH by organocatalysis with >99 % regioselectivity. TBDPS, Boc, and BOM groups were sequentially introduced into the 4-O-acyl-glucopyranoside at C(6)-OH, C(2)-OH, and C(3)-OH, resp., with ca. 100 % regioselectivity in each step.
European Journal of Organic Chemistry published new progress about 85618-21-9. 85618-21-9 belongs to alcohols-buliding-blocks, auxiliary class Tetrahydropyran,Chiral,sulfides,Alcohol, name is (2R,3S,4S,5R,6S)-2-(Hydroxymethyl)-6-(octylthio)tetrahydro-2H-pyran-3,4,5-triol, and the molecular formula is C14H28O5S, SDS of cas: 85618-21-9.
