Highly Functional Group Compatible Rh-Catalyzed Addition of Arylboroxines to Activated N-tert-Butanesulfinyl Ketimines
摘要:
The rhodium-catalyzed addition of readily accessible arylboroxines to N-tert-butanesulfinyl ketimines derived from oxetan-3-one, N-Boc-azetidin-3-one, and isatins proceeds In high yields with excellent functional group compatibility. Moreover, high diastereoselectivities are observed for the additions to the N-sulfinyl ketimines derived from isatins.

ring‐opening process features low catalyst loading, mild reaction conditions, broad functional group compatibility, high enantioselectivity, and the capability to generate chiral quaternarycenters. The highly functionalized desymmetrization products are versatile chiral buildingblocks in organic synthesis.

The oxetane ring is useful in drug discovery as a bioisostere for both the geminal dimethyl group and the carbonyl group. A convenient, straightforward approach to access structurally diverse 3-aminooxetanes through the reactivity of oxetan-3-terf-butylsulfinimine and the corresponding sulfinylaziridine is described.
