reactions of dialkyl diselenides proceeded by the combined use of 2,4‐dinitrobromobenzene and NaBH4 in the presence of an amine, a thiol, and a carboxylic acid. A ε‐N,N,N‐trimethyllysine derivative was synthesized from a selenohomocysteine derivative by using the SNAr reaction as a key step, followed by oxidation, olefin metathesis with 4‐iodobutene, reduction, and substitution with trimethylamine.
