Article abstract of DOI:10.1248/cpb.46.906

A new synthetic route to Erythrina alkaloids by formation of ring C utilizing a Pummerer-type intramolecular cyclization was developed. The N- (2-phenylthioethyl)-dioxopyrroline (3) was converted to 13 in five steps with satisfactory overall yield (69%) b
