The synthesis of a propellane derivative of salinosporamide A having increased stability under physiological-like conditions is reported. The synthesis took advantage of a substrate-controlled stereoselective Ugi 4-center 3-component reaction to construct the required syn-bicyclic pyroglutamic acid framework. (C) 2009 Elsevier Ltd.
