  In one aspect, the disclosure relates to methods for preparation of terpene and terpene-like molecules. In a further aspect, the disclosure relates to the products of the disclosed methods, i.e., terpene and terpene-like molecules prepared using the disclosed methods. Intermediates for the synthesis of a wide variety of terpenoids are γ-allyl Knoevenagel adducts or quasi γ-allyl Knoevenagel adducts are disclosed. In various aspects, methods of preparing terpenoids through these intermediates are disclosed. The methods can comprise α-alkylation of an allylic electrophile followed by ring-closure metathesis to a polycyclic terpenoid structure. In a further aspect, the disclosure pertains to terpenoid frameworks, and compounds prepared via disclosed oxidation and substitution reactions on the disclosed terpenoid frameworks. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

  在一个方面，本公开涉及制备萜烯和类萜烯分子的方法。在另一个方面，本公开涉及所述方法的产物，即使用所述方法制备的萜烯和类萜烯分子。公开了合成各种萜烯类化合物的中间体γ-烯丙基Knoevenagel加合物或准γ-烯丙基Knoevenagel加合物。在各个方面，公开了通过这些中间体制备萜烯类化合物的方法。这些方法可以包括烯丙基亲电试剂的α-烷基化，然后通过环闭合重排生成多环萜烯结构。在另一个方面，本公开涉及萜烯类骨架，以及通过公开的氧化和取代反应在所述萜烯类骨架上制备的化合物。本摘要旨在作为在特定领域进行搜索的扫描工具，并不旨在限制本公开。
