我们在这里报告了Rh(III)催化吲哚和吡咯的CH活化/环化的新策略,用于特权杂环的发散合成。带有氧化性双齿引导基团的吲哚和吡咯基简单地衍生为N-羧酰胺可以实现Rhodacycle的形成以及后期的炔烃,烯烃和重氮化合物的氧化还原中性环化反应,从而获得五元和六元稠合杂环,例如pyrimido [1,6- a ]吲哚-1(2 H)-one,3,4-dihydropyrimidoido [1,6- a ] indol-1(2 H)-one和1 H-咪唑并[1,5- a ]吲哚-3(2 H)-那些。进行了动力学同位素效应研究,并提出了合理的机理。此外,该方案适用于克规模的简明合成5-HT3受体拮抗剂。
The invention provides antitumour compounds of formula (I), wherein R
1
is an aromatic substituent; R
2
is hydrogen or a substituent when the dotted line is absent, or R
2
is absent when the dotted line represents a bond to give a double bond between the nitrogen which bears R
2
and the carbon which bears R
3
; R
3
is an oxo group ═O when the dotted line is absent or is a substituent when the dotted line represents a bond to give a double bond between the nitrogen bearing R
2
and the carbon bearing R
3
; R
4
is hydrogen or a substituent; and pharmaceutically acceptable salts thereof.
