Chiral building blocks

WebNotably, either antipode of a desired chiral building block can be generated from a single enantiomer of the auxiliary simply by altering the order of electrophile addition. WebDiazoxide BPDZ-44 was found to be a tissue selective ATP-sensitive potassium channel opener, resulting in inhibition of important physiological processes such as insulin release or muscle tone and contractility. The straightforward synthesis of BPDZ-44 used (S)-2-amino-3-methylbutane as a chiral building block in a key step (Figure 2). 6
