Beta-subunit of baboon chorionic gonadotropin. Continuous flow Fmoc-polyamide synthesis of the C-terminal 37-peptide

Abstract

The synthesis of a 37-peptide fragment derived from the carboxyl terminal of the beta-subunit of baboon chorionic gonadotropin has been accomplished by the continuous flow Fmoc-polyamide solid phase method. The use of N alpha-fluorenylmethoxy-carbonyl-glutamine with its sidechain protected by the 4,4'-dimethoxybenzhydryl group enabled successful incorporation of this residue onto a hydroxymethyl linkage agent without apparent side reaction.
