A series of γ-butyrolactone derivatives, including some spiranic ones, was obtained through desymmetrization of the corresponding prochiral 3-substituted cyclobutanones via Baeyer–Villiger monooxygenase (BVMO)-catalyzed oxidation. After reaction optimization using several commercial enzymes, both antipodes of various lactones were synthesized in most cases with >90% conversion and >80% enantiomeric

The present invention relates to spirocyclic compounds of formula I, namely spirocyclic (1H-pyrazol-4-yl)-3-( 1-(2,6-dichloro-3- fiuorophenyl) ethoxy)pyridin-2-amines having protein kinase inhibitory activity, and methods of synthesizing and using such compounds. Preferred compounds are c-Met and/or ALK inhibitors useful for the treatment of abnormal cell growth, such as cancers.
provides a platform for the rapid preparation of a wide variety of chiral spirocyclic building blocks. The chemoselective functionalization of the carbon‐boron bond in the products, including a stereospecific sp3‐sp2 Suzuki–Miyauracross‐coupling reaction, provides a powerful tool to control the directionality and the nature of the exit vectors in the spirocyclic framework.
