Abstract
Primary amides condense with aliphatic aldehydes (2 equiv.) in the presence of trifluoromethanesulfonic acid to give β-amido aldehydes.

1H NMR spectra of the separated diastereoisomeric acids obtained by
aerial oxidation of the aldehydes in entry 1 exhibit couplings for the
vicinal methine hydrogen atoms of 10 and 5 Hz (isolated as the minor
diastereoisomer), and 3 and 5 Hz (major diastereoisomer). The former
values are consistent with the syn-isomer in a preferred conformation in
which the amido and aldehyde groups are antiperiplanar, and the
methine hydrogen atoms are disposed trans(J= 10 Hz). (‘syn’ refers to
relation of α-alkyl and β-amido groups, the aldehyde being drawn as
part of the ‘backbone’ of the product.) Such assignm ents are consistent
with those for other β-amido carbonyl compounds: H. Estermann and D. Seebach, Helv. Chim. Acta, 1988, 71, 1824 Search PubMed.
