New approaches to Pictet-Spengler-type cyclisation reactions
A modified Pictet–Spengler synthesis has been developed, which alleviates the problems associated with the classical synthesis. A-methoxyurethanes were used as precursors, and cyclisation initiated under mild Lewis acid conditions in non-aqueous media at room temperature. Precursors with unactivated...
