  Synthesis of enantiomerically pure bay-region 10,11-diol 8,9-epoxide diastereomers of the carcinogen dibenz[a,h]acridine

  摘要：

  The present study describes the synthesis and configurational assignment of four enantiomerically pure, bay-region 10,11-diol 8,9-epoxide diastereomers 14-17 of dibenz[a,h]acridine (1) from the corresponding optically pure trans-10,11-dihydroxy-10,11-dihydrodibenz[a,h]acridine enantiomers 6 and 7. Racemic trans-10,11-di-hydroxy-10, 11-dihydrodibenz[a,h]acridine (3) was resolved via its conversion to the diastereomeric bis((-)-methyloxy) esters, separation of the diastereomers by short bed/continuous developing preparative TLC, and finally saponification of the individual diastereomers. Assignment of (10R,11R)-absolute configuration to (-)-trans-10,11-dihydroxy-10,11-dihydrodibenz[a,h]acridine (6) was achieved through the application of exciton circular dichroism technique to the bis[p-(dimethylamino)cinnamic] ester 13 of its tetrahydro analogue 11.
