Palladium-catalyzed reduction of an allylic amine : a formal access to both diastereoisomers of cyclopentenyl glycine
摘要:
The easily accessible bicyclic amines 3 (exo or endo) are regioselectively transformed to the methyl esters of the diastereoisomers (1c or 1d) of N-benzyl cyclopentenyl glycine by reaction with hydride donors (mainly NaBH3CN) in the presence of a palladium(0) catalyst.

N-Substituted 2-azanorbornenes undergo a 9-borabicyclo [3.3.1]nonane induced fragmentation in tetrahydrofuran giving rise to cyclopentenylmethyl amines (cf 3 and 5).
