  完成了 (S)-(+)-cryptaustoline 的不对称合成，发现其旋转符号与天然 «S»-(-)-材料不同。发现先前分配的绝对配置不正确，现在已更正。立体化学的逆转是通过一种不寻常的方式实现的，包括 (S)-(+)-laudanosoline (3) 环化为 (R)-(-)-cryptaustoline ((-)-1c)。通过氧化一系列月桂醇油碱的氘代衍生物来探索该机制，所有这些衍生物都在所得的隐孢子碱中保留了氘

  Many possible 1-benzyltetrahydroisoquinolines have been examined as possible advanced precursors of the alkaloids hasubanonine (1) and protostephanine (2) in Stephania japonica plants, but none was incorporated significantly. Administration of various precursor molecules having only one aromatic ring, such as tyrosine, has demonstrated that both alkaloids are derived from two different C6–C2 biogenetic

  已经研究了许多可能的1-苄基四氢异喹啉类化合物，它们是Stephania japonica植物中生物碱hasubanonine（1）和protostephanine（2）的可能的高级前体，但没有明显掺入。施用仅具有一个芳香环的各种前体分子（例如酪氨酸）已证明这两种生物碱均来自两个不同的C 6 -C 2生物遗传单位。随后无法进一步引入1-苄基四氢异喹啉和双苯乙胺，这表明（a）改性的1-苄基异喹啉或（b）三加氧的C 6 –C 2中间体建筑模块。设计用于检查第一种可能性的前体，例如1-苄基-3,4-二氢异喹啉或1-苄基-1-羧基四氢异喹啉，未合并到（1）和（2）中，而两个3'，4'，5'-掺入三氧化的2-苯基乙胺。这些发现允许进一步描述对生物碱（1）和（2）的后续前体的需求。
