prepared from 1-chloroalkyl phenyl sulfoxides or chloromethyl phenyl sulfoxide and carbonyl compounds, with alkyl- or arylamines afforded α-amino ketones or α-amino aldehydes in good yields. Treatment of thus obtained α-arylamino ketones with weak Lewis acid led to 2,3-disubstituted indoles.
α,β-环氧亚砜的氨解,很容易从 1-氯烷基苯基亚砜或氯甲基苯基亚砜和羰基化合物制备,用烷基胺或芳基胺以良好的产率得到 α-氨基酮或 α-氨基醛。用弱路易斯酸处理由此获得的α-芳基氨基酮产生2,3-二取代的吲哚。
