[1,3]二氧戊环并[4,5-B]吡啶-6-硼酸 | [1,3]dioxolo[4,5-b]pyridin-6-ylboronic acid | 1019767-68-0 | C6H6BNO4 | 166.929 |
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.
