Fantastic paper from Brooks Able at Berkeley using an organic catalyst to achieve high molecular weight for poly(THF) via cationic ring-opening polymerization. The low ceiling temperatures of these polymers make them attractive targets for reversible polymerizations, but it has previously been really hard to get to the molecular weights required for good mechanical properties. #chemistry #polymers #JACS https://pubs.acs.org/doi/10.1021/jacs.5c18359

A novel bifunctional molecule induces selective nitrosation of BTK. Mechanistically, it first covalent bind to BTK and the release NO, which yielded in the nitrosation of a cysteine side chain. Published in #JACS by Jiangbing Wu, Zhangjian Huang and coworkers (#China)

When you think of a reaction between an acid and an alcohol, you think of an ester as the product. MacMillan and co-workers from Princeton have now described a different pathway: Selective decarbonylative C-C coupling via a metal-catalyzed photoredox reaction. Read more about this in JACS:

Novel enantioselective #synthesis of rubriflordilactone B by Gui and colleagues from the Chinese Academy of Science published in #JACS
This is already the second total synthesis of this group, with an interesting reaction cascade as the key reaction in this process.

Luo et al. from Tsinghua University (#China) report in #JACS a novel method to create enantioenriched Ξ±-amino aldehydes using a chiral amine catalyst and iridium photocatalysis. Through this strategy Ξ±-amino aldehydes with up to 93% ee could be synthesised and subsequently stabilised via analogues formation (e.g. through Wittig reaction).

Novel Synthetic Approach for the Synthesis of Pyrroloiminoquinones | Stephan Scheeff

The total synthesis of aleutianamin was enabled by a new convergent coupling reaction.

Another total synthesis in the spotlight: Already early this year Mingji Dai and his research team described the total synthesis of heilonine in #JACS (doi: 10.1021/jacs.3c13492). This synthesis is short and elegant, using multiple C-H functionalisations and a Nazarov cyclisation for their key step.
