Enanatioselective Switch and Potential Applications in Biocatalysis
CHIMIA, 2023 Enantioselectivity has always been a key feature of enzymatic synthesis. In some cases, when enzymes are not strictly enantioselective, by tuning the reaction conditions it is possible to induce an enantioselective switch.

Enantioselective Synthesis of (−)‐10‐Hydroxyacutuminine
Angewandte Chemie International Edition, 2022 AbstractAn enantioselective synthesis of (−)‐10‐hydroxyacutuminine is reported. Central to our strategy is a photochemical [2+2] cycloaddition that forges two of the quaternary stereocenters present in the acutumine alkaloids. A subsequent retro‐aldol/Dieckmann sequence furnishes the spirocyclic cyclopentenone.

New development in the enantioselective synthesis of spiro compounds.
Chemical Society Reviews, 2018 The enantioselective synthesis of spirocycles has long been pursued by organic chemists. Despite their unique 3D properties and presence in several natural products, the difficulty in their enantioselective synthesis makes them underrepresented in ...
