<p><P>PROBLEM TO BE SOLVED: To provide a method by which anthraquinone derivatives having low reactivity are mutually and directly subjected to ring condensation by dimerization and a polycyclic compound can stereoselectively be mass-produced in good yield. <P>SOLUTION: The method for producing the condensed polycyclic compound is carried out as follows. Anthraquinones in which the 1-, 2-, 7- and 8-positions may be unsubstituted and the 3- and 6-positions are substituted with a free hydroxy group or substituted with a hydroxy group protected by a protecting group with the unsubstituted 4- and 5-positions are exposed to high pressure of 1×10<SP>8</SP>to 1×10<SP>10</SP>Pa. Two molecules thereof are mutually bound with carbon atoms at the 10-position and carbon atoms of either one of the 4- and 5-positions to provide a dimer. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
