Diels-Alder Reactions of Furo [3,4-b] 1,4-benzodioxins: An Efficient Approach to Substituted Dibenzo [b,e][1,4] Dioxins
摘要:
In view of their potential biological properties, different substituted dibenzo [b,e][1,4] dioxins have been synthesized using Diels-Alder reactions. This required the preparation of furobenzodioxins and further dehydration of the bicyclo-adducts of the cycloaddition.
An efficient synthesis of new dioxygenated isoquinolines is reported. The novelty of this approach derives from its use of tricyclic-nitril (3) as a building block in a synthetic sequence of seven steps for the preparation of the tetracyclic isoquinoline (14) and itsderivatives. The isoquinoline 16 was 10-fold more active against leukemia L1210 than the corresponding tetrahydroisoquinoline 14.
