A Michaelis‐Arbuzov‐Type Pathway to a Protected 2ʹ‐Deoxy‐2ʹ‐Selenomethyl‐Adenosine‐3ʹ,5ʹ‐Phosphoroselenolate Guanosine Dinucleotide for Use in Modified m7G Cap Synthesis

Chemistry – A European Journal, Volume 32, Issue 10, 9 March 2026.
Here we report a synthesis of the dinucleotide 4 for a projected future total synthesis of the m7G cap 1. Highlights of the route include: 1) a 3ʹ‐H‐phosphonate/5ʹ‐selenocyanate Michaelis‐Arbuzov coupling to forge the 3ʹ,5ʹ‐phosphoroselenolate; 2) an Amosova reductive selenomethylation to install the 2ʹ‐SeMe; 3) a solid CPR II 5ʹ‐O‐phosphitylation; and

Synthetic Studies Towards Darobactin A

Chemistry – A European Journal, Volume 32, Issue 10, 9 March 2026.
The urgent need for new antibiotics led us to develop a new methodology for the synthesis of the natural product darobactin A selectively targeting gram‐negative bacteria. This study provides new insights into the synthesis of strained indole‐containing macrocycles.
