Abstract
The conversion of the metal organyls of 1,3-benzdioxole, pyrido[2.3-d]-1.3-dioxole and pyrido[2.3-b]-1.4-dioxene using lactimethers did not prove successful. The N-alkyl-2-aryl-pyrrolidines 10a-c, 11a-c, 12a, 13a and 14a were synthesized from the aldehydes 4a-c via the γ-ketonitriles 7a-c and the 2-aryl-⊿1-pyrrolidines 8 a-c; in some cases, the recovery was high.
摘要:使用内酯醚对1,3-苯并二氧杂环己烷基金属有机物、吡啶并[2.3-d]-1.3-二氧杂环己烷基金属有机物和吡啶并[2.3-b]-1.4-二氧杂环己烯基金属有机物进行转化并不成功。N-烷基-2-芳基吡咯烷10a-c、11a-c、12a、13a和14a通过醛4a-c经γ-酮腈7a-c和2-芳基-⊿1-吡咯烷8a-c合成;在某些情况下,收率很高。
