一般說明
Hmb protection of amide bonds has been shown to inhibit aggregation of "difficult" peptides in Fmoc SPPS, thereby leading to products of increased purity [1,2,3,4,5,6]. Retention of Hmb groups on the cleaved peptide can greatly improve the solubility of protected peptide fragments [7,8] and otherwise intractable sequences [9,10,11]. Furthermore, using a Hmb-protected derivative for incorporation of the residue linked to the carboxy group of Asp or Asn residues has been found to suppress formation of aspartimide and piperidide related by-products [12,13,14]. For a comparison of the efficiency of Hmb and pseudoprolines in preventing aggregation, see [15].
