摘要:
The utility of Tbdms (t-butyldimethylsilyl) ethers, prepared conveniently in a one-pot procedure from N(alpha)-Fmoc (9-fluorenylmethoxycarbonyl) and N(alpha)-Z (benzyloxycarbonyl) hydroxyamino acids, is demonstrated: peptide bond formation and esterification to 4-alkoxybenzylalcohol resin are achieved readily with these derivatives. The lability of the Tbdms ethers to various reagents enables selective deprotection of the hydroxyl side-chains after peptide chain assembly, desirable, e.g., for phosphorylation or glycosilation.
