Abstract

b -thienyl alkylcarbamates of formula (I) (where R = 1-4C alkyl, and R' = H or 1-4C alkyl). (I) are prepd. e.g. from an opt. substd. dihydroresorcinol by (a) condensing with an alkyl halide, (b) halogenating to give 2-allyl 3-chlorocyclohex-2-ene-1-one, (c) cyclising with NaSH, (d) dehydrogenating with S, and (e) forming the carbamate, e.g. with an isocyanate.
