Indoline-2-thiones 1a-b,d,f,h, which have at least one hydrogen at the 3-position reacted with α-halo ester 2a-d, α-halo ketones 2e-f, and a-bromoacetonitrile 2g to give 2-alkylthioindole derivatives 3–11. In a similar manner treatment of 3,3-disubstituted indoline-2-thiones 1c,e with α-halo esters 2a,c,d and α-halo ketone 2e gave 2-alkylthioindolenines 12–16. Treatment of 1,3,3- trisubstituted indoline-2-thiones
在3位上具有至少一个氢的二氢吲哚啉-2-硫酮1a-b,d,f,h与α-卤代酯2a-d,α-卤代酮2e-f和a-溴乙腈2g反应生成得到2-烷基硫代吲哚衍生物3-11。以类似的方式处理3,3-二取代的二氢吲哚-2-硫酮的1C,电子与α卤代酯2A,C,d和α卤代酮2E,得到2- alkylthioindolenines 12-16。用溴乙酸乙酯2a处理1,3,3-三取代的二氢吲哚-2-硫酮1g,i导致原料的回收。假吲哚的脱硫14与三苯基膦得到2-亚烷基二氢吲哚19。
