Abstract

Condensation of N‐trimethylsilylindole with methyl N‐trimethylsilyloxymethylpyroglutamate is the best method to obtain methyl N‐indolylmethylpyroglutamate. Friedel‐Crafts cyclization of the corresponding acid yields a new ketone (1,2,3,5,11,11a‐hexahydroindolizino[7,6‐b] indole‐3,11‐dione).
