Derivatives of grindelic acid: from a non-active natural diterpene to synthetic antitumor derivatives [PDF]
Using several reactions that include homologations and asymmetric epoxidations as well as Ugi and Huisgen couplings, we generated a small focused library of new derivatives from the labdane-type diterpene grindelic acid. These compounds were evaluated as

A deep‐red‐excited osmium(II) photosensitizer (Os2) induces immunogenic cell death (ICD) under 740 nm irradiation and triggers robust anti‐tumor immune responses both in vitro and in vivo. ABSTRACT Immunogenic cell death (ICD), which converts tumor cells into their own vaccine, plays a pivotal role in the development of novel anticancer therapies. Here,

New Short Strategy for the Synthesis of the Dibenz[b,f]oxepin Scaffold
In this report a short and efficient synthesis of the dibenz[b,f]oxepin framework through intramolecular SNAr and McMurry reactions is described. The diaryl ethers required for the McMurry reaction have been obtained in good yields under microwave ...
