Asymmetric 1,2‐carbamoyl rearrangement of lithiated 2‐alkenyl carbamates has been investigated. Deprotonation of chiral 2‐alkenyl oxazolidine carbamates with sec‐butyllithium in ether at −78 °C followed by warming of the resulting 1‐lithio‐2‐alkenyl derivatives to room temperature resulted in 1,2‐carbamoyl rearrangement to provide α‐hydroxy amides. The rearrangement proceeded with excellent diastereoselectivity...
