13C NMR data for several simple coumarins are reported. The ysvn effect of a 5-methoxy substituent on the C-4 chemical shift was observed and measured. The effects of an 8-iodo substituent on the chemical shifts of the carbons of the coumarinic skeleton are discussed.

The carbamate 8 was reacted with appropriate Ξ²-keto esters in a Pechmann reaction giving the coumarin derivatives 9-11 bearing 4-nitrobenzylcarbamoyl triggers. These compounds were assessed as potential indicators of nitroreductase activity.
