| Research Abstract |
Features of the microwave-assisted organic reaction are that the reproducibility is high in order to uniformly heat in reaction system. In the pericyclic reaction, its application to Diels-Alder reaction and Claisen rearrangement reaction was examined. However, that application to the electrocyclic reaction was not yet reported.
We have examined the efficient synthesis of biological activity heterocyclic compounds through a construction of isoquinoline based on a microwave-assisted thermal electrocyclic reaction of an 6π-electrocn system.
(1)Effect of microwave to thermal electrocyclic reaction of azahexatriene system
(2)Synthesis of the new furo[3,2-h]isoquinoline alkaloid, TMC-120A, B, and C possessing inhibitory activity against the interleukin-5.
(3)Synthetic study of phenanthridine alkaloid, trispheridine
(4)Synthetic study of azaanthraquinone alkaloid, scorpinone
We established the new synthetic method of isoquinolines based on a microwave-assisted thermal electrocyclic reaction. This method was applied, and the total. synthesis of the furo[3,2-h]isoquinoline alkaloid, TMC-120A,B,C, phenanthridine alkaloid, trispheridine, and azaanthraquinone alkaloid, scorpinone were achieved.
