   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 ...

   May 5, 2020 · Using these enzymes, we demonstrate the synthesis of a broad range of primary amines, with conversions up to >97% and excellent enantiomeric excess. Temperature dependent studies showed that these homologues also possess greater thermal stability compared to other enzymes within this family.

   Reaction Scheme V. PCP via Ritter reaction: This method is generally easy, and starts with inexpensive and commercially available 1-phenylcyclohexene, or alternately from1-phenylcyclohexanol (PCOH) (ref. 10, 56, 58, 65). PCOH or phenylcyclohexene is reacted with sodium cyanide and H2SO4 to give N-formyl PCA in about 50-60% yield.

   Why do arylcyclohexamines cause misperception?

   • The underlying mechanism of the emergence phenomena caused by arylcyclohexamines appears to be due to their depressive effects on visual and auditory relay nuclei in the medial geniculate and inferior colliculus, respectively, leading to misperception and/or misinterpretation of visual and auditory stimuli [ 287, 288 ].

   How do arylcyclohexamines affect NMDA receptor antagonism?

   • The effects of NMDA receptor antagonism by arylcyclohexamines result in modulation of glutamatergic transmission [ 147 ]. Their primary effects, including anesthesia, analgesia, and psychotomimetic properties, relate to this action (see Pathophysiology, below).

   What are arylcyclohexamines?

   • Arylcyclohexamines (also known as arylcyclohexylamines) are a group of compounds that contain a cyclohexamine unit with an aryl moiety, typically a phenyl ring, attached to the same atom to which the amine group is linked (see Fig. 1 ).
