resin in a traceless fashion is described. Azole substrates II are assembled in a one-pot condensation reaction of azoles and aldehydes with a resin-bound carbamyl chloride. Treatment of the azolyl-carbamate II with boron trifluoride etherate under thermal or microwave-assisted solvolysis conditions afforded 2-substituted azoles. [reaction: see text]
