ACETYLENIC FRAGMENTATION OF ACYL DERIVATIVES OF THE FISCHER BASE

Indolenium salts, which readily undergo cleavage in aqueous alkali to give a monosubstituted acetylene and 1,3,3-trimethyl-2-oxindole, are formed when acyl derivatives of the Fischer base are heated with phosphorus oxychloride.Various aryl- and hetarylacetylenes can be conveniently obtained by this method.
