The asymmetricsynthesis of tetracyclic pyrroles bearing a tetrasubstitutedcarbonstereocenter has been accomplished through a one-pot sequence that comprises a cross metathesis reaction followed by a tandem cycloisomerization/ intramolecular Pictet-Spengler-type reaction. This sequence took place on conveniently functionalized chiral amino acids to render the final products in good overall yields
