The first enantioselective total synthesis of (+)-()-dihydroperiphylline was achieved from ()-β-phenyl-β-alanine, prepared by chelation controlled phenylation of the Schiff base, by a new route involving 13-membered lactam formation via iminium cyclization.
由()-β-苯基-β-丙氨酸通过对席夫碱的螯合控制苯基化制备的(+)-(-)-二氢环茶碱的第一个对映选择性全合成是通过一种新的途径,该途径涉及通过亚胺基形成13元内酰胺的新方法环化。
