Enamino-thiones of the general type ArC(S)CH:CHNR2,3(Ar=phenyl p-methoxyphenyl and p-bromophenyl NR2= pyrrolidinyl piperidinol were prepared by reacting the corresponding enaminones 2 with 2,4-bis-(4-methoxyphenyl) 1,3,2,4-dithiadiphosphetane 2,4-disultide 1. The compounds 3 were reacted with methyl iodide and ethyl iodide to give exclusively S-alkylated iminium iodides 4 and 5, in quantitative overall
一般类型ArC(S)CH:CHNR 2,3(Ar =苯基对甲氧基苯基和对溴苯基NR 2 =吡咯烷基哌啶醇)的烯胺硫酮是通过使相应的烯胺酮2与2,4-双-(4 (3-甲氧基苯基)1,3,2,4-二硫代二膦二环2,4-二硫化物1.使化合物3与甲基碘和乙基碘反应生成S-烷基化亚碘化碘4和5,总定量收率为N苯基-2 ,3,5,6,7,8-六氢-4-喹啉硫酮8和2-甲基-N苯基-2,3,5,6,7,8-六氢-4-喹啉甲硫酮9用碘代甲烷,碘代甲烷和苄基溴进行烷基化,得到S-烷基化的六氢喹啉卤化物。10和11分别高产。详细讨论了类型4和5的化合物的立体化学。
