摘要：

A β-tripyrane XI and cyclic β-trispyrrole XII were obtained by means of a novel two-step pyrrole synthesis from pentacarbonyl(1-amino-1-phenylmethylene)-chromium IV via an intermediate iminocarbene complex VI. VI adds alkynes VIIa-e to give the 1H-pyrroles Xa-e. Xe undergoes a rapid self-condensation with the formation of XI and XII. © 1990.
