Reaction of zinc enolates e.g. (6) derived from arylacetates with 2-aryl-3-methoxymaleic anhydrides e.g. (3) gives intermediates viz (8) which can be dehydrated to Z-and E-isomers of permethylated pulvinic acids; treatment of the latter with trimethylsily
New Syntheses of Pulvinic Acids via Reformatsky-type Reactions with Aryl methoxymaleic Anhydrides

The reaction of zinc enolates, viz (13), derived from arylacetates with 2-aryl-3-methoxymaleic anhydrides gives β-hydroxy ester intermediates viz(17) which can be dehydrated to Z- and E-isomers of permethylated pulvinic acids.Thus, the intermediate (17) d
