  Investigation of a model for 1,2-asymmetric induction in reactions of .alpha.-carbalkoxy radicals: a stereochemical comparison of reactions of .alpha.-carbalkoxy radicals and ester enolates

  摘要：

  The stereochemical course of reductions and allylations of alpha-carbalkoxy radicals with chiral centers at the beta-position are reported. Radicals without polar substituents, with alkoxyl or acetoxyl groups, and with hydroxyl groups at the beta-position were examined. Reactions showed selectivities ranging from low (50:50) to high (99:1). The results are discussed in terms of transition-state models that emphasize the importance of (1) allylic conformational analysis (minimization of A1,3 and A1,2 strain), (2) torisonal strain (minimization of eclipsed interactions), and (3) stereoelectronic effects.

  Catch me if you can: The ClpP protease mediates protein homeostasis and can be efficiently inhibited by β‐lactones. A combination of molecular docking, mutagenesis, activity‐based protein profiling, and kinetics studies now reveals the mechanism of ClpP inhibition. A hydrophobic pocket next to the active site allows binding of long aliphatic and aromatic residues. The preferred stereoisomer binds into
