Paragraph 0097-0101, (2021/09/21)
The invention relates to the technical field of chemical drug synthesis, and discloses an application of an intermediate or a preparation method thereof in synthesis of vinorchin, adopts a modular synthetic strategy, adopts the compound D with 1 ring structures and C20 quaternary carbon centers, 5 (i.e. the compound 5) as a synthesis building block. The operation is simple and reaction conditions are easy for large-scale amplification effect.

A concise synthesis of melohenine B and O-ethyl-14-epimelohenine B, from eburnamonine, was achieved via a biomimetic diastereoselective singlet oxygen-mediated oxidative cleavage of the indole C2-C7 bond. These studies enabled the assignment of the absolute configuration of the natural products. In line with a proposed biosynthetic pathway, the resulting nine-membered ring containing products could be converted to the corresponding quinolones.
