β¦ Synopsis
The cycloaddition of the enol ethers of cyclic ketones with isoquinolinium salts is the key step in a general preparation of interesting tricyclic naphthalene derivatives, The cycloaddition of isoquinolinium salts with electron-rich alkenes was developed by BradsherJ' and it was further extended by Falck,' Sammes,3 and ourselves. 4 Bradsher had reported a limited number of examples where cyclic

A high yielding green protocol for the synthesis of tricyclic oxaza quinolinium salts has been developed using Amberlite IRA 402(OH) in water. This method is more effective compared to previously reported phase-transfer catalytic (PTC) condition in terms of yield of the product, reaction time and ea
