FAILURE TO VERIFY A REPORTED SYNTHESIS OF THE ACONITINE SKELETON
Cornforth, Sir John,Pengelly, Tony
, p. 2213 - 2216 (1982)
Attempts to verify the first three stages of a claimed synthesis of the aconitine skeleton (Samir Chatterjee, Tetrahedron Lett. 3249 (1979) have given totally different results.It is concluded that the reported products of these three stages were not in fact obtained.
