N-heterocyclic carbene catalyzed stereoselective glycosylation of 2-nitrogalactals

An efficient N-heterocyclic carbene catalyzed glycosylation of 2-nitrogalactals with alcohols and phenol has been developed for the first time. A wide variety of 1,2-cis-2-nitroglycosides can be obtained with good to excellent yields and high to excellent

Conjugate addition of phenols to 2-nitrogalactal - Synthesis of O-(2-acetamido-2-deoxygalactosyl) tyrosine

2-Nitrogalactal derivative 1 afforded 2-deoxy-2-nitrogalactopyranosides on treatment with phenol and substituted derivatives under base catalysis. Transformation of the nitro group into the amino and the acetamido groups and O-deprotection could readily be performed, thus providing aryl 2-acetamido2-deoxygalactopyranosides 5 and 6 in high yields and with good stereoselectivities. The same reaction sequence could also be successfully applied to N-Boc-protected tyrosine methyl ester, to afford the O-galactopyranonsyl tyrosine derivative 10. Wiley-VCH Verlag GmbH & Co.
