A Palladium-catalyzed three-component-coupling strategy for the differential vicinal diarylation of terminal 1,3-dienes

A palladium-catalyzed intermolecular vicinal diarylation of terminal 1,3-dienes using aryldiazonium tetrafluoroborates and arylboronic acids is reported. Using this technology, two different arenes are regioselectively introduced in a vicinal fashion across the terminal alkene of a variety of terminal 1,3-dienes at ambient temperature. Through the action of a chiral bicyclo[2.2.2]octadienyl ligand at -20 C, good enantioselectivity has also been achieved.

Total synthesis, biological evaluation of dendrodolides A?D and their analogues

A concise total synthesis of dendrodolides A?D (1?4) has been accomplished in 10 steps from commercially available (R)-propylene oxide and 3-buten-1-ol as starting materials. The key steps involved in the synthesis are Jacobsen hydrolytic kinetic resolution, epoxide ring opening with 2-allyl-1, 3-dithiane, Yamaguchi esterification and ring-closing metathesis (RCM). In addition, a series of ester derivatives were prepared utilizing Yamaguchi esterification at the C-3 position of the dendrodolide core and screened for their efficacy against cancer cell lines.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 4254-15-3

Concise synthesis of stagonolide-F by ring closing metathesis approach and its biological evaluation

The first total synthesis of 9-membered macrolide, stagonolide-F (3), starting from commercially available 1,5-pentane diol is reported. A combination of Jacobsen’s hydrolytic kinetic resolution (HKR) and Sharpless epoxidation is used for the creation of two stereogenic centers, while ring-closing metathesis (RCM) strategy was used for the construction of the lactone ring. The molecule synthesized exhibited potent antifungal, antibacterial and cytotoxic activities against all the tested strains.
