摘要：

The synthesis of the ester (12) and lactone (19) via reductive photocyclisation of the enamide (3), kinetically controlled alkylation of the furopyridone (4), and reductive cleavage of the γ-lactones (10) and (14) illustrates a new general method for the preparation of the ipecac and heteroyohimbine alkaloids.
