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.

Chiral rings made easy: Chiral azetidin‐3‐ones have been easily prepared from chiral N‐propargylsulfonamides, which in turn are readily accessible through chiral sulfinamide chemistry (see scheme). Using tert‐butylsulfonyl as the protecting group avoids unnecessary deprotection and reprotection steps, and allows its removal from the azetidine ring under acidic conditions.
