Interaction of methyl N-tryptophylnicotinate bromide with the lithium salt of ethyl α-(trimethylsilyl)acetate and acid-catalyzed cyclization has yielded a tetracyclic ester, whose condensation with acetaldehyde has produced ethyl vallesiachotamate.Reactions of lithiated, alkylthiolated esters with the nicotinate salt (followed by cyclization) have afforded related adducts.Ester-to-aldehyde group conversion has to the alkaloid vallesiachotamine in the 19Z and 19E forms.
