highly selective C-Holefination of directing-group-free indolines (C5) and tetrahydroquinolines (C6) by Pd/S,O-ligand catalysis. In the presence of the S,O-ligand, a wide range of challenging indolines, tetrahydroquinolines, and olefins was efficiently olefinated under mild reaction conditions. The synthetic potential of this methodology was demonstrated by the efficient olefination of several indoline-based

A novel process for the preparation of 7-acylindolin-2-ones of the formula: ##STR1## wherein R is hydrogen, halogen, lower alkyl, lower alkoxy, or trifluoromethyl; R.sup.1 is lower alkyl, alkylphenyl, cycloalkyl, or aryl; and R.sup.2 is hydrogen, lower alkyl or benzyl is provided. The compounds are useful as intermediates in the preparation of 2-amino-3-acylphenylacetic acid compounds which possess pharmaceutical properties.
