"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."^^ . "2003-01-01" . . "9 SPEC" . . "Synlett"^^ . . .
