Protic acid (HClO4 supported on silica gel)-mediated synthesis of 2,3-unsaturated-O-glucosides and a chiral furan diol from 2,3-glycals.

Aditi Agarwal et al.

The Journal of organic chemistry, 69(18), 6137-6140 (2004-09-18)

Perchloric acid supported on silica gel acts as an excellent reagent system in converting glucals into 2,3-unsaturated-O-glucosides in good to excellent yields in short reaction time with good alpha selectivity. Primary, secondary, and allylic alcohols, phenols, and thiols react with

Attempts to improve the overall stereoselectivity of the Ireland-Claisen rearrangement.

Chi-Li Chen et al.

Organic letters, 11(2), 409-412 (2009-01-09)

With focus on the steric effects present in the transition states for the [3,3]-sigmatropic rearrangement, the substrate 5 has been designed to improve the overall stereoselectivity of the Ireland-Claisen rearrangement. Experimentally, it has been found that (1) only Z-6 rearranges

Glycal glycosylation and 2-nitroglycal concatenation, a powerful combination for mucin core structure synthesis.

Jürgen Geiger et al.

The Journal of organic chemistry, 72(12), 4367-4377 (2007-05-17)

A 3,4-O-unprotected galactal derivative having bulky 6-O-TIPS protection (compound 2) could be regioselectively 3-O-glycosylated with O-(galactopyranosyl) trichloroacetimidates; depending on the protecting group pattern stereoselectively alpha- and beta-linked disaccharides were obtained. With O-(2-azido-2-deoxyglucopyransyl) trichloroacetimidate as donor (compound 10A), glycosylation of 2
