Über 2‐substituierte Resorcindimethyläther

Abstract: Eingegangen am 2. Juni 1967 2-Lithium-resorcindimethylather (1) wird mit Halogenen, Pseudohalogenen, Alkylhalogeniden, Alkenylhalogeniden, Halogenathern, Epoxiden, Aldehyden, Ketonen und Saurechloriden zu 2-substituierten Resorcindimethylathern umgesetzt ; die Verbindungen werden charakterisiert.AnlaiBlich unserer Untersuchungen in der Cumarin-Reihe1) waren wir an der Darstellung von 2-substituierten Resorcinen interessiert. Ihre Darstellung bereitet gewisse Schwierigkeiten, da Resorcin und dessen Ather nach d… Show more

“…A standard procedure was used to transform final compounds into their hydrochloride salts. The following intermediates have been prepared following literature methods: 5-methoxy-2-tetralone (Cornforth & Robinson 1949), 3-(1-piperazinyl)-1,2-benzisoxazole (Yevich et al 1986), 1-(2-chloroethyl)-3-methoxybenzene (Kato et al 1993), 1-(2-chloroethyl)-2-methoxybenzene (Kato et al 1993), 1-(2-chloroethyl)-2,6-dimethoxybenzene (Boltze & Dell 1967), 2,3,4-trimethoxyphenylacetic acid (Arndts et al 1994). All reactions were carried out under an atmosphere of nitrogen.…”

“…Direct chlorination of an aryllithium intermediate did not form the anticipated chloride, but rather the -ClO derivative. 21 N-Chlorosuccinimide (NCS) 22 and arylsulfonyl chlorides [23][24][25] have been used with some success (Table 3, entries 1-3), but the most versatile reagent is C 2 Cl 6 . Several nitrogen heterocycles have been successfully chlorinated in 64-82% yields using this reagent [26][27][28][29] (Table 3, entries 4-7).…”
