Synthesis of functionalised azecine and azonine derivatives via an enolate assisted aza Claisen rearrangement
摘要:
This paper describes the synthesis of functionalised azecine and azonine derivatives incorporating the adrenaline motif. In a key step, an enolate assisted aza Claisen rearrangement was employed to interconvert from 6- and 5-membered heterocycles to their corresponding 10- and 9-membered lactams. (C) 2005 Elsevier Ltd.

Adding an aryne to a tertiary allylamine affords o‐allylaniline products of an aza‐Claisenrearrangement. The aryne simultaneously provides the π component for the rearrangement and the quaternization event that lowers the activation energy for the sigmatropic shift. The reaction was applied to the synthesis of medium‐ring benzannulated amines (see scheme).

The present application provides novel aminoindane compounds and methods for preparing and using these compounds. These compounds are useful in treating pain and/or itch in patients by administering one or more of the compounds to a patient. The methods include administering a compound of formula (I) or (II) and a TRPV 1 receptor activator. In one embodiment, the TRPV 1 receptor activator is lidocaine.

An efficient and stereoselective synthesis of pyrrolidine-, piperidine-, and azepane-type N-heterocycles is described by the intramolecular Pd(0)-catalysed cyclisation of amino allylic carbonates. The use of chiral ligands gave the corresponding heterocyclic derivatives having er values that were from moderate to good.

iminium ion promoter from alpha-amino nitriles, is an efficient additive in the Bruylants reaction involving vinylic Grignards. Improved yields of allylic amines were obtained when the starting alpha-amino nitrile was treated with this silver salt prior to its reaction with the vinylic Grignard. This improvement was not observed in the case of acetylenic Grignards. The reactivity of other vinyl organometallics
