Robust and scalable synthesis of functionalized 1,3‐disubstituted pyridylcyclobutanes (including nicotine analogues) is developed, which relies on double alkylation of pyridylacetonitriles.

and thiols using N‐(trifluoromethylthio)phthalimide under mild, metal‐free conditions is described. A series of trifluoromethanesulfenamides and unsymmetricaldisulfides is prepared from the corresponding aliphatic and aromatic amines and thiols in good yields. The reactions are operationally simple and tolerate a wide variety of functional groups. Trifluoromethanesulfenamides and disulfides belong to

were introduced in Ex4, while also utilizing various linkers, so that it was possible to identify Cbi conjugates of Ex4 that exhibit improved binding and agonist activity at the GLP-1R. An optimized conjugate (22), comparable with Ex4, was successfully screened and subsequently assayed for insulin secretion in rat islets and in vivo in shrews for glucoregulatory and emetic behavior, relative to Ex4.

A biomimetic strategy for the monofunctionalization of a calix[6]arene core is described. It is based on host–guest chemistry (mimicking the Michaelis–Menten adduct in enzymes) and allows the finely tuned pre‐organization of the substrate (an alkyne) with respect to the reactant (three azido groups introduced at the calixarene large rim). It is shown that the thermal Huisgen reaction implemented in

The present invention relates to quinazoline containing zinc-binding moiety based derivatives that have enhanced and unexpected properties as inhibitors of epidermal growth factor receptor tyrosine kinase (EGFR-TK) and their use in the treatment of EGFR-TK related diseases and disorders such as cancer. The said derivatives may further act as HDAC inhibitors.
