首次报道了开口型葛根碱B的全合成。该生物碱的四个立体中心,其中三个是四元的,由Diels-Alder反应、叔醇的非对映选择性氰化和表面选择性硝酮1,3-偶极环加成反应立体选择性地生成。
The first total synthesis of the opened-typeKopsiaalkaloid grandilodine B is reported. Four stereocenters of this alkaloid, three of them quaternary, are stereoselectively generated by a Diels–Alder reaction, a diastereoselective cyanation of tertiary alcohol, and a facial-selective nitrone 1,3-dipolar cycloaddition.
