Notes:
The cyclisation of either 1a or 3a with acid yielded the cis-fused erythrinanone 2; no trans-isomer could be detected. The structure of this unexpected product was determined by NMR. and confirmed by an X-ray analysis. Various tetrahydro- and hexahydro-2-indolinones were prepared to facilitate the interpretation of the NMR.-spectrum of 2.
