S-Fluorenylmethyl protection of the cysteine side chain upon Nα-Fmoc deprotection
Deprotection of an Nα-Fmoc-protected glycocysteine derivative 7 with an excess of morpholine unexpectedly led to the fluorenylmethyl-protected thioether 8 in high yield. The suggested mechanism for this reaction comprises the addition of the cysteine thiolate on the exocyclic double bond of dibenzof...
