    • Typical Procedure for the Cyclisation. The products 3a-e were dissolved in MeOH (3 mL/mmol) and treated with 3 N methanolic HCl (3 mL/mmol, prepared by mixing one part of aq HCl (12 N) with four parts of MeOH). The reaction was stirred at r.t. until TLC control indicated complete conversion of the starting material. All solvents were evaporated under reduced pressure and the product 4a-e was recrystallised from THF-n-pentane.
