enantiospecific access to synthetically valuable 10-N-substituted camphors (amines and secondary amides) has been developed. The synthetic method uses camphor as the starting enantiopure material and takes place in five individual steps with a high overall yield. The process involves a stereocontrolled double-Wagner–Meerwein-rearrangement strategy to generate key-intermediate 10-(triflyloxy)camphor, a peculiar and
