A bit late to the party, but still interesting. In 2023 Yong Qin and co-workers from Sichuan #University in #China published in #JACS the first #totalsynthesis of the terpene garryine.
The total synthesis heavily relies on [Pd] catalyzed cross couplings including a enantioselective variant of an intramolecular Heck coupling.
The draft has been added to my page some years ago, but only finished today.

Mingji Dai (Emroy University, USA) recently published the first #totalsynthesis of the #alkaloid stemocurtisine in the journal #JACS (10.1021/jacs.6c12593) using a palladium catalysed carbonylation for lactone formation.
I summarised his synthetic route on my collection of total syntheses and added two exercises for advanced #chemistry #students

🎁 Happy 80th birthday to K. C. Nicolaou—master of “the art of total synthesis”, whose landmark syntheses of Calicheamicin, Taxol, Brevetoxin B, Epothilone, and Vancomycin helped shape modern organic chemistry. #TotalSynthesis #OrganicChemistry

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. -
Joseph Tuccinardi and John Wood from Baylor University (#USA), introduced a novel strategy to efficiently synthesize the core scaffold of aleutianamine. Their study involved a vinylogous Mukaiyama-Michael reaction cascade using two previously unknown coupling partners. Published in #JACS

Computer-aided synthesis: R. Shenvi and C. Li published in #Nature the total synthesis of 25 picrotoxanes. Their 1,5-HAT key reaction was challenged by β-scission, therefore DFT based calculations helped to design usable intermediates.

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.

Total Synthesis of Pleurotin (JACS Au, Y. Q. Long 2024)
Pleurotin is a benzoquinone meroterpenoid that was first isolated in the late 1940s. Since that time, several total syntheses of this compound have been reported. Recently, Ya-Qiu Long and his team from Soochow University (#China) published a novel synthetic route in the journal JACS Au.

Stasseriolides are a class of polyketide natural products with interesting biological activities, but they are limited in natural abundance. A recent synthesis of stasseriolides A-D by Alois Fürstner's group at the Max Planck Institute für Kohlenforschung reported in Angewandte Chemie employed ring-closing alkyne metathesis, providing access to the natural products and enabling the preparation of analogues.

Terpenoids are a large class of secondary #NaturalProducts, with some possessing an interesting polycyclic core that has attracted research interest. Researchers from #Shandong #University in #China led by Ze-Jun Xu (徐泽军) and Hong-Xiang Luo (娄红祥) have now reported the #TotalSynthesis of platensilin and platensimycin, as well as the formal synthesis of platencin, using a biomimetic approach from a common precursor.

My Reading Tip of the Week:
Scabrolide A, a polycyclic marine natural product, has fascinated chemists due to its highly constrained structure. Recently, Pengfei Hu and colleagues from Westlake University in Hangzhou, China, published an innovative radical cascade strategy for efficiently synthesizing the scaffold of this polycyclic compound.
Divergent Synthesis of Scabrolide A and Havellockate via an exo-exo-endo Radical Cascade

Researchers (Rahul Choudhury et al.) from the Academy of Scientific and Innovative Research in #India reported in the journal #OrganicLetters the total synthesis of benzo[g]isochromene stereodiads. Their synthesis using a TiCl4 promoted #Aldol coupling showed that the previously reported absolute structure did not agree with the structure of the natural product and a revision was suggested.

Melognine was thought to be a highly complex alkaloid with a polycyclic ring system. Yui Irie and Satoshi Yokoshima (Nagoya University, #Japan) published a total synthesis of the proposed structure in the journal #JACS. However, the synthesised structure turned out to have different analytical properties. The authors concluded that melognine is actually identical to melodinine L. Check out the intriguing total synthesis route on JACS:

If you have some time, take a look at the total synthesis of Hunterine A by Elliot Hicks, Kengo Inoue and Brian Stoltz published in #JACS (#OpenAccess). Very elegant synthesis and late-stage cyclization strategy.

The #TotalSynthesis of highly condensed polycyclic terpenoids has been a hot topic in #Chemistry recently. Yandong Zhang (#Xiamen University, #China) and co-workers now were able to synthesize such complex terpenes by epoxide-ene cyclization, oxygenation, and subsequent skeletal rearrangement.
