3-Alkylindoles were prepared in one step from indoles and ketones via a convenient reductive alkylation procedure using triethylsilane and trichloroacetic acid. Under this particular condition, unsubstituted indoles could be tolerated to afford good yields of 3-sec-alkylation products.

## Abstract An efficient approach has been developed for the synthesis of an isofervenulin analogue **1** employing a one‐pot condensation‐substitution reaction of a chlorocarboethoxytriazine (electrophile) with a urea (nucleophile). The resulting cyclization reaction resulted in the synthesis of a
