14) It is noteworthy that Regan et al. described a very concise synthesis of racemic epibatidine. The key step was a reductive Pd-catalyzed Heck-type coupling of the known starting materials olefin (LVI) and 2-chloro-5-iodopyridine (LVII). The desired exo-isomer (LVIII) was formed stereoselectively.
