A five-step approach to the preparation of the β-carboline CDE ring system of lavendamycin is detailed and is based on: (1) thermal cycloaddition of 3,5,6-tricarbomethoxy-1,2,4-triazine with the pyrrolidine enamine of o-bromopropiophenone followed by (2) implementation of a newly developed palladium (O) mediated β-carboline synthesis.
