Synthesis of 2-arylacrylates from pyruvate by tosylhydrazide-promoted Pd-catalyzed coupling with aryl halides

Important synthetic intermediates and direct precursors of the prophen class of anti-inflammatory agents, 2-arylacrylates are prepared in one step from ethyl pyruvate by employing the recently developed Pd-catalyzed cross-coupling between tosylhydrazones

Herbicidal methods and compositions comprising epoxy compounds

A method of combating undesired plant growth at a locus is disclosed, the method comprising applying to the locus a compound of general formula: STR1 where R1 and R2 independently represent a hydrogen atom or an optionally substituted alkyl or alkenyl group or R1 and R2 together represent an optionally substituted alkyl or alkenyl chain; R3 represents an optionally substituted saturated or unsaturated homocyclic or heterocyclic group; and Z represents a group --COOR4 where R4 represents a hydrogen atom, a cation or an optionally substituted alkyl, alkenyl, alkynyl or aryl group, or Z represents a group --CHO. The use of a compound of general formula I as a herbicide and a herbicidal composition are also disclosed.
