Abstract: PURPOSE: A method for manufacturing pentacyclic compound using a simple method through intracyclization reaction of A-alkynyl B-ketoester compound are provided to manufacture the pentacyclic compound at high yield. CONSTITUTION: A method for manufacturing pentacyclic compound includes a step of manufacturing the pentacyclic compound represented by chemical formula 1 under the presence of an iron catalyst. In the chemical formula 1 or 5, R is selected from C1-C7 alkyl, C3-C8 cycloalkyl, C6-C20 aryl, or C3-C20 heteroaryl. R^1 is selected from C6-C20 arylamino and the C1-C7 alkoxy. R^2 is selected from hydrogen, C1-C7 alkyl or C6-C20 aryl.
