Thieme–IUPAC Prize

Your paper should present high-impact research results including, for example:

• new methods with a broad range of applicability to synthetic problems
• significant improvements of existing methods (e.g., through catalysis)
• the application of synthetic methods to large-scale production
• ecologically benign and economically improved versions of existing synthetic transformations
• new bond-forming reactions

The prize is awarded by the Editorial Boards of SYNTHESIS, SYNLETT, and SynOpen, represented by their Editors-in-Chiefs Mark Lautens, Debabrata Maiti, and Thierry Ollevier. The winners of the three awards receive prize money and a framed certificate. Papers are nominated by the Editorial Board and Advisory Board members of all three journals. Each Board Member may select a maximum of three papers per journal and year. The decision about the prize winners will be made at the beginning of each year (considering papers published in the previous year) and announced publicly at the end of January.

It is our great pleasure to announce that the SynOpen Best Paper Award 2024 is being awarded to Benjamin Stokes and co-workers at Santa Clara University (USA) for their publication Pd-Catalyzed Transfer Hydrogenation of Alkenes Using Tetrahydroxydiboron as the Sole Hydrogen Donor.

In announcing the selection, Thierry Ollevier, Editor-in-Chief of SynOpen, commented: "The development of new transition-metal-catalyzed hydrogenation conditions is especially important for pharmaceutical and fine chemistry in general. The publication of Professor Stokes and co-workers describes the palladium-catalyzed transfer hydrogenation of alkenes using tetrahydroxydiboron as the sole hydrogen donor. The reaction mediated by palladium(II) acetate as a convenient precatalyst and run in mild conditions was successfully applied to a variety of alkenes to afford the corresponding alkanes in high yields. The results reported in this SynOpen Most Innovative Paper 2024 will be very instructive for the future development of other atom-economical hydrogenation processes. The scientific value of the publication was pointed out, but also the quality and the clarity of its presentation. It is an excellent contribution that we are proud to have published in SynOpen."

It is our great pleasure to announce that the SYNTHESIS Best Paper Award 2024 is being awarded to Yota Sakakibara, Kei Murakami and co-workers at Kwansei Gakuin University and JST PRESTO (Japan) for their paper Photoredox-Enabled Synthesis of a-Alkylated Alkenylammonium Salts, which was included in the Special Issue PSRC-10 (10th Pacific Symposium on Radical Chemistry).

In revealing this year’s winning paper, Mark Lautens, Editor-in-Chief of SYNTHESIS, wrote: “The publication of Professor Murakami and co-workers outlines an interesting use of ammonium salts containing a vinyl bromide as a reagent for addition to 1,1-diaryl ethylenes. Reaction occurs under photoredox conditions and offers a way to preserve and directly use ammonium salts in novel reactions. As one editor put it, “ammonium salts are a somewhat forgotten group to carry through many classes of reactions.” Murakami is changing that perspective with this excellent contribution.”

We are delighted to announce that the SYNLETT Best Paper Award 2024 is being awarded to Sunkyu Han and co-workers at Korea Advanced Institute of Science and Technology (KAIST) for their article Total Synthesis of 4a-Hydroxyallosecurinine and Securingine F, Securinega Alkaloids with a C4-Hydroxy Handle for Biofunctional Derivatizations, which was published as part of the Cluster Biomimetic Synthesis.

In announcing the selection, Debrabati Maiti, Editor-in-Chief of SYNLETT, stated: “This manuscript was selected as the "best paper" for its significant contribution to natural product synthesis.It reports the first total syntheses of 4¢-hydroxyallosecurinine and securingine F, complex securinega alkaloids with promising biological activity. The authors address the challenge of the lack of functional handles in these alkaloids by strategically introducing a hydroxy group at the C4 position. Their elegant synthetic route features key transformations like a stereoselective aza-Michael addition, a creative HAT-mediated C2 epimerization, and an efficient 1,2-amine shift. They further streamlined the synthesis with a one-pot Mitsunobu-based approach. This work enables future biofunctional derivatizations for target identification and ADC development, opening new avenues for research in this important area. The manuscript is well-written and clearly presented, showcasing the authors’ technical expertise and the broad potential of their methodology.”
