TL;DR: In this article, it was proposed that these salts result from an intramolecular reaction of initially formed alkylation products, in which case the initial alkyl product undergoes an intramerolecular condensation with subsequent hydrogen chloride elimination.

TL;DR: The intramolecular reaction of Nα-formyltryptophan to 3,4-dihydro-β-caroline-3-carboxylic acid was realized with high yield either in trifluoroacetic acid or in formic acid.
Abstract: The intramolecular reaction of Nα-formyltryptophan to 3,4-dihydro-β-carboline-3-carboxylic acid is realized with high yield either in trifluoroacetic acid or in formic acid – concentrated hydrochlo...

TL;DR: In this article, the adduct of diethoxyoxophosphoranesulphenyl chloride (I) and cyclohexene-4-carboxylic acid chloride (IV) yields, via an intramolecular reaction, nearly equal amounts of 4-acetylthio-6-oxabicyclo[3.2.1]octan-7-one (XIV) and 4- acetoxy-6thiabicyCLo[ 3.2]deconvariant [3.1]-decon
