The N-acyl hydroxymethylpyrrole amino acid analogues 5–7 and 9 were synthesized via a mild DMAP catalysed acylation of pyrrole-2-carboxaldehyde with an acid chloride followed by formyl group reduction with Zn(BH4)2. The N-acyl substituted hydroxymethylpyrroles are activated on hydrolysis to give an electrophilic species that can be trapped by an external nucleophile.
