Synthesis of certain Amids likely to possess Anaesthetic Properties

The phamnacollogical actions of amide type locanl anaesthetics , diphenylacotic acid estors and pivalic acid esters and amides are outlined.Methods of properation of intermediates were described and discussed.The following unavailable intermediates were prepared:1) Benzoylphenylcarbinol (benzoin).2) Dibenzoyl (Benail) .3) Diphenylglycolic acid (Benzilic acid).4) Diphenylacetic acid .5)Diphenyacetyl achlorids.6)2,3- Dimethy _2,3 – butandiol hexhydratr (pinacol hydrate).7) 3,3 –Dimethyl-2-butanone (pinacolone).8) Trimethlacetic acid (pivalic acid).9) Trimethylacetyl chloride(pivaloy chloride).10)3,2-Dimrthylbenzoic acid (hesitylenic acid).
