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

(Chemical Equation Presented) 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 stere

O-glycosyl amino acids by 2-nitrogalactal concatenation - Synthesis of a Mucin-type O-glycan

Base-promoted Michael-type addition of N-Boc- and N-Fmoc-protected serine and threonine esters to 2-nitrogalactal derivatives 2 and 26 led highly selectively to α-glycosides 4a-d and 27a,c, respectively. Ensuing transformation of threonine derivative 4d a

Nitroglycal concatenation: A broadly applicable and efficient approach to the synthesis of complex O-glycans

Base-catalyzed glycosylations provide the basis for a new and general entry to the synthesis of mucin-type O-glycans. The desired α-linked 2-acetamidoglycosyl amino acids B are accessible selectively starting from glycals of type A. Fmoc = 9-fluorenylmeth
