“…Transformation of compound 28 into the fully O -methylated and O -sulphated final product required a different pathway. It is known that uronic acid residues are prone to suffer β -elimination in the basic conditions of the etherification 46 , 49 . Therefore, prior to the oxidative formation of the glucuronide residue, compound 28 was deacetylated under Zemplén conditions and the obtained 32 was methylated in the presence of methyl iodide and sodium hydride.…”

“…An analogous triacetylated glucosyl donor 36 was also used for comparison with 33 . Donors 33 and 36 were derived from 31 23 in a straightforward manner. For donor 33 , the PMB ether at C‐6 was established by a reductive ring‐opening of the 4,6‐anisylidene group,24 which was followed by silylation to give 32 in high yield.…”

“…A reakciókörülények optimálása során az 31-es tioglikozid akceptort 9 18 ) glikozilezésével elõállítottam az öt új védett pentaszacharidot (6-10) valamint a korábban más reakcióúton elõállított pentaszacharid-triszulfonsavat (52; 10. ábra). A glikozilezési reakciók jó hozammal teljes sztereoszelektivitással mentek végbe.…”
