    摘要: The present invention relates to a process for preparing a class of sulphonamides which are aspartyl protease inhibitors. These compounds find therapeutic use in the treatment of the human immunodeficiency virus (HIV). This virus is the causative agent for acquired immunodeficiency syndrome (AIDS). The synthetic procedure of the present invention involves a convenient and efficient process utilising base coupling, decarboxylation and reduction steps to produce the desired compounds in good yield. One advantage of the process of the present invention is its convergent approach which leads to improved yields. The procedure also enables stereoselectivity to be controlled to a high degree, thus avoiding the need for resolution procedures where chiral products are formed.
