An efficient eight‐step semisynthetic approach towards nonracemic pyrrolo‐allocolchicinoids starting from natural colchicine was developed by exploiting Pd‐catalyzed domino Sonogashira coupling/5‐endo‐digcyclization of a 2‐iodo‐trifluoroacetanilide intermediate to build up the heterocyclic ring system. TheN‐Me substitution of the pyrrole ring enhanced the antitumor activity of the prepared molecules by 2–3 orders of magnitude. Among the active compounds, theN‐methylated colchicinoid exhibited powerful cytotoxic and antiproliferative properties at concentrations < 1 nm.
