Synthesis of 2-Arylethylamines by the Curtius Rearrangement
摘要:
2-Arylethylamine derivatives were synthesized using the Curtius reaction and with three different methods of preparing the acyl azide functional group. Carbamates derived from isocyanate were convenient protecting groups for alkylation of amines. Starting from benzaldehyde, amphetamine was prepared in three steps through an oxazolidin-2-one intermediate in 62% overall yield.

Hapten-carrier conjugates capable of eliciting anti-hapten antibodies in vivo to amphetamines are disclosed. Methods of preparing the hapten-carrier conjugates and therapeutic compositions are also disclosed. A therapeutic composition containing the hapten-carrier conjugate is useful in the treatment of addiction to amphetamines. Passive immunization using antibodies raised against conjugates of the instant invention also is disclosed. The therapeutic composition is suitable for co-therapy with other conventional drugs for treatment of amphetamine abuse.
