Article abstract of DOI:10.1248/cpb.42.204

Oxalylation of the enamino-ester 13 derived from the L-dopa derivative 12 gave the dioxopyrroline of (6S)-configuration (15A) diastereoselectively (50- 60% diastereomer excess). This was converted to a mixture of erythrinans of (5S,6R,7R,10S) and (5R,6S,7
