The palladium(0) catalysed coupling of 2-bromocyclopentene-1-carboxaldehyde N,N-dimethylhydrazone 1 with vinylzinc halides and with 2-furyl- and 2-thicnylzinc halides provides a route to the corresponding 2-vinyl- and 2-heteroaryl-cyclopentene-1-carboxaldehyde dimethylhydrazones. These cyclise thermally to 6,7-dihydro-5H-2-pyrindines (e.g., 3).
2-溴环戊烯-1-甲醛N,N-二甲基hydr 1与乙烯基锌卤化物以及2-呋喃基和2-噻吩基锌卤化物的钯(0)催化偶联为相应的2-乙烯基-和2-杂芳基-提供了一条途径环戊烯-1-羧甲醛二甲基hydr。它们热环化成6,7-二氢-5 H -2-吡啶啉(例如3)。
