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.

A series of 1-(2-hydroxyethyl)- and 1-(3-hydroxyethyl)-3-substituted ureas and thioureas were synthesized. 1-(3-Hydroxyerhyl)-3-acylthioureas were shown to be specific substrates for alcohol dehydrogenase in vitro.
