alcohol give N- (1′-phenyl-2′-hydroxyethyl)-2,3-naphthylenedicarboximide 1. The 2,3-naphthylenedicarboxylic acid reacted with thionyl chloride give the 2,3-Naphthalenedicarboxylic acid cyclic anhydride rather than corresponding 2,3-naphthalenedicarboxylic acid dichloride, the former reacted with amino alcohol also give compound 1. The later two strategies cannot give the target bisoxazoline.
摘要 研究了含萘基的手性C 2 对称取代双恶唑啉配体的合成。2,3-萘二甲酸乙酯与氨基醇反应,所得酰胺用SOCl 2 处理,然后在甲苯中与Et 3 N反应,得到所需的双恶唑啉。2,3-萘二甲腈与氨基醇反应生成 N-(1'-苯基-2'-羟乙基)-2,3-萘二甲酰亚胺 1. 2,3-萘二甲酸与亚硫酰氯反应生成 2,3-萘二甲酸环酐而不是相应的2,3-萘二甲酰二氯,前者与氨基醇反应也得到化合物1。后两种策略不能得到目标双恶唑啉。
