Application of vicarious nucleophilic substitution to the total synthesis of dl-physostigmine
Rege, Pankaj D.,Johnson, Francis
, p. 6133 - 6139 (2003)
A concise, highly efficient formal total synthesis of dl-physostigmine is described, using a relatively simple method that should be adaptable to the synthesis of homologous members of this type of alkaloid. The key step in the synthesis is a new vicariou
