Eight-membered ring templates for stereoselective radical cyclizations
TLDR
The ratio of cyclization to reduction of the cyclodec-6-enylmethyl radical depends critically on the alkene geometry as mentioned in this paper, which is a structural feature of the taxane diterpenes.About:

The McMurry Coupling and Related Reactions
Takeshi Takeda,Akira Tsubouchi +1 more
TL;DR: McMurry coupling has been recognized as one of the most efficient methods for the synthesis of alkenes from carbonyl compounds as discussed by the authors, which can be applied to the preparation of various alkenets that are otherwise difficult to prepare.

Synthesis of camphor based chiral crown ethers and their interactions with amino acid derivatives
TL;DR: In this paper, three camphor based crown ethers have been prepared, starting from (1R)-camphorquinone, in which 2-and 3-endo-substituents are used to regulate the availability of the endo-l8-crown-6 face for binding organic guests and the bridge head methyl group is available to impart enantioselectivity at the exo-face.
