- Synthesis of 6-Azaspiro[4.3]alkanes: Innovative Scaffolds for Drug Discovery
-
New scaffolds for drug discovery, 6-azaspiro[4.3]alkanes, have been synthesized in two steps from four-membered-ring ketones: cyclobutanone, thienone, N-Boc-azetidinone (Boc = tert-butoxycarbonyl), etc. The key transformation was the reaction between electron-deficient exocyclic alkenes and an in-situ generated N-benzylazomethine ylide.

- Oxetanes in drug discovery: Structural and synthetic insights
-
An oxetane can trigger profound changes in aqueous solubility, lipophilicity, metabolic stability, and conformational preference when replacing commonly employed functionalities such as gem-dimethyl or carbonyl groups. The magnitude of these changes depends on the structural context. Thus, by substitution of a gem-dimethyl group with an oxetane, aqueous solubility may increase by a factor of 4 to more than 4000 while reducing the rate of metabolic degradation in most cases. The incorporation of an oxetane into an aliphatic chain can cause conformational changes favoring synclinal rather than antiplanar arrangements of the chain. Additionally spirocyclic oxetanes (e.g., 2-oxa-6-aza-spiro[3.3]heptane) bear remarkable analogies to commonly used fragments in drug discovery, such as morpholine, and are even able to supplant the latter in its solubilizing ability. A rich chemistry of oxetan-3-one and derived Michael acceptors provide venues for the preparation of a broad variety of novel oxetanes not previously documented, thus providing the foundation for their broad use in chemistry and drug discovery.
