acids to afford bicyclic beta-alkoxy amides. The intermediate acylimines are prepared through cyanohydrin ether hydrozirconation and acylation of the resulting metalloimine, providing an operationally facile one pot protocol. A two-step variant of the procedure has also been developed to effect cyclizations from acylimines that undergo competitive tautomerization.
