PCOH or phenylcyclohexene is reacted with sodium cyanide and H2SO4 to give N-formyl PCA in about 50-60% yield. N-formyl PCA is readily hydrolyzed in either acid or base conditions to give PCA, which can then be alkylated to give PCP and other analogs, as illustrated in Scheme IV.
Example: Synthesis of PCE (N-ethyl-1-phenylcyclohexylamine): A mixture of 100 g of anhydrous ethylamine and 220 g of cyclohexanone was kept 16 hours, then shaken with solid KOH. The lower oil layer, which comprises the imine ( N-cyclohexylidenethylamine), was then removed by decantation.
General Reaction. Example. Mechanism. The mechanism for the Hofmann rearrangement is quite complex. The mechanism starts with the deprontation of the primary amide by a base. The nitrogen is brominated during an S N 2 reaction with Br 2 to produce an N-bromoamide. Bromide is eliminated as a leaving group to produce a electron deficient nitrene ...
