Abstract
Glitazones are an important class of prescription drugs used to treat type II diabetes (T2DM). These drugs reduce blood sugar levels by targeting the peroxisome proliferator-activated receptors (PPARs) and act as insulin sensitizers. There are currently several FDA-approved glitazones. This review describes the synthetic strategies used for manufacturing of these drugs, in particular focusing on synthesis by commercially available thiazolidine-2,4-dione (TZD) on both bench and industrial scales. Further, an insight into the chiral approaches reported for enantiomers of pioglitazone and rosiglitazone is given. A brief description about the history of glitazones is also provided. This short review is aimed at providing a holistic understanding of the challenges and issues associated with implementing an effective strategy for synthesis of these drugs.
