The synthesis of a subtype-selective inhibitor BACE-1 inhibitor is presented. One of the key transformations in this sequence is the conversion of a thiourea to the bicyclic 1,3-aminooxazine. This article outlines the development and application of this method to the target molecule as well as further exploration of its scope and mechanism.
