Article abstract of DOI:10.1016/S0040-4039(00)80063-5

Aldol reaction of methyl α-isocyanocarboxylates (CNCH(R)COOMe: R=H, Me, Et, i-Pr, Ph) with paraformaldehyde in the presence of 1 molpercent of a chiral (aminoalkyl)ferrocenylphosphine-gold(I) complex gave optically active 4-alkyl-2-oxazoline-4-carboxylates (up to 83percent ee) which were readily hydrolyzed to α-alkylserines.
