9-Ethyl-3,4,5,6,9,10-hexahydroacridine-1(2H),-8(7H)-dione (5) and its N-allyl analogue (6) were formed in a one-step ring-forming reaction from both the 2-and/or N-allyl derivatives of 3-aminocyclohex-2-enone (1)–(4) and from the bisenaminone (7), obtained from the N-allylenaminone (2), on treatment with PdCl2(MeCN)2.
9-乙基-3,4,5,6,9,10-六氢ac啶-1(2 H),-8(7 H)-二酮(5)及其N-烯丙基类似物(6)形成一个步骤环形成来自两个反应的2-和/或ñ 3-氨基环己-2-烯酮( -烯丙基衍生物1) - (4),并从bisenaminone(7),从所获得的ñ -allylenaminone(2), PdCl 2(MeCN)2处理的方法。
