Abstract
Under the influence of electron impact, esters of saturated keto acids of the indole series undergo the fragmentation typical for 3-acylindoles, whereas esters of unsaturated and aromatic 3-indolyl keto acids have specific mass spectra that reflect the peculiarities of their structure and the mutual orientation of the substituents.
