This is the first time that most of the products described herein have been prepared via benzoin‐type condensation. or in a thesis or dissertation provided that the correct acknowledgement is given

and you may need to create a new Wiley Online Library account. In these reactions, 3‐hydroxy‐3‐methylbutan‐2‐one (methylacetoin) was used as the activated acetaldehyde donor, while 4‐hydroxy‐4‐methylhexan‐3‐one was employed for the first time as the precursor of activated propionaldehyde.

In particular, in cross‐benzoin condensations of aromatic reactants and mixed aromatic/aliphatic reactions, use of these enzymes has resulted in high levels of chemo‐, regio‐ and stereoselectivity. * If you are not the author of this article and you wish to reproduce material from Technical support issues arising from supporting information (other than missing files) should be addressed to the authors. The intermolecular cross-benzoin and acyloin condensation reactions are powerful approaches to α-hydroxy carbonyls in a single step. Dipartimento di Scienze Farmaceutiche, Sezione di Chimica Generale e Organica “A. However, their potentiality suffers from the occurrence of side reactions including self-condensation and the formation of the undesired cross-acyloin.

The development of an asymmetric cross-benzoin condensation via enzymatic cross-coupling reactions is a synthetically useful process.Highly enantiomerically enriched mixed benzoins can be obtained from two different substituted benzaldehdyes using benzaldehyde lyase as a catalyst (Scheme \(\PageIndex{2}\)).
