Carpino, Louis A. published the artcile9-Fluorenylmethoxycarbonyl amino-protecting group, COA of Formula: C19H21N, the publication is Journal of Organic Chemistry (1972), 37(22), 3404-9, database is CAplus.
The 9-fluorenylmethoxycarbonyl group (FMOC) is a new amino-protecting group, which is stable toward acids and catalytic hydrogenation but readily cleaved under mildly basic, non-hydrolytic conditions. The FMOC group may be introduced by reaction of the amine with 9-fluorenylmethyl chloroformate. A number of protected amino acid derivatives were coupled with other amino acids or esters by use of the corresponding N-hydroxypiperidine esters. Deblocking of the FMOC group was carried out with liquid NH3 or at room temperature with piperidine, morpholine, ethanolamine. etc.
