Treatment of α,β-epoxy sulfoxides, prepared from 1-chloroalkyl phenyl sulfoxides and carbonyl compounds, with various kinds of alkane- or arenethiolates afforded α-sulfenylated ketones in good yields. This method also offered a novel procedure for a synthesis of α-sulfenylated aldehydes.
α,β-Epoxy Sulfoxides as Useful Intermediates in Organic Synthesis. III. A Novel Synthesis of α-Amino Ketones and α-Amino Aldehydes by Aminolysis of α,β-Epoxy Sulfoxides
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.
