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.
二烷基二硒化物的化学选择性S N Ar反应是通过在胺,硫醇和羧酸的存在下联合使用2,4-二硝基溴苯和NaBH 4进行的。甲ε- N,N,N-从一个selenohomocysteine衍生物通过使用S合成-trimethyllysine衍生物Ñ的Ar反应作为关键步骤,随后氧化,烯烃易位与4- iodobutene,还原,和取代与三甲胺。
