✦ Synopsis

Abstract

Efficient methods are described for synthesis of isotopomers of the water‐soluble, photolabile 1‐acyl‐7‐nitroindoline 5 with either ^13^C in the carbonyl of the acyl substituent or ^15^N in the nitro group. The isotopic incorporations were verified by IR difference spectroscopy coupled with flash photolysis.
