, p. 915 - 921 (2007/10/02)
Friedel-Crafts reaction of aromatic compounds with ethyl α-chloro-α-(methylthio)acetate (1) gave ethyl α-(methylthio)arylacetates (2), which were readily converted into ethyl arylacetates (3) by reductive desulfurization with Raney nickel or zinc dust-acetic acid.The reactions were applied to the syntheses of ibufenac (5) and alclofenac (6), which are anti-inflammatory agents.
ELECTROPHILIC AROMATIC SUBSTITUTION BY PUMMERER REACTION OF α-SULFINYLACETATE
Tamura, Y.,Choi, H.-D.,Shindo, H.,Uenishi, J.,Ishibashi, H.
, p. 81 - 84 (2007/10/02)
Treatment of a mixture of aromatic compound and ethyl α-(methylsulfinyl)acetate (5) with p-toluenesulfonic acid under continuous removal of separated water brought about an intermolecular aromatic substitution to give ethyl α-(methylthio)arylacetate (6).S
