With L-DOPA as the starting chiral phenylalanine derivatives, construction of the skeleton of Phthalascidin was studied. Firstly, starting from L-DOPA and 3,4-dimethoxyphenylalanine, an amide 〓 was obtained, and a modeling cyclization reaction was carried out but failed to give the anticipated product.
