Re. Dansodanquah et al., SYNTHESIS OF OXA ANALOGS OF PORPHOBILINOGEN (PBG) AS PROBES FOR MECHANISTIC STUDIES OF PBG DEAMINASE, Tetrahedron, 49(36), 1993, pp. 8195-8210
Three oxa analogs of porphobilinogen (PBG) 2, 27, and 29 were synthesi
zed from 3-hydroxymethylfuran. The target molecules were prepared by i
ntroducing first the beta-acetate sidechain, then constructing propion
ate side chains on the furan nucleus into which the aminomethyl group
was introduced at position 2 via the corresponding aldehyde.
