        abstract = {The reaction of o,o?-dialkyl-substituted aryl isonitriles with N-propargyl-6-iodopyridones provides 11H-indolizino[1,2-b]quinolin-9-ones with significant regioselectivity in favor of the more crowded product. The usefulness of the method is illustrated with a regioselective synthesis of (20S)-7-trimethylsilyl-9-isopropyl camptothecin.}
