The Hendrickson 'POP' reagent and analogues thereof: synthesis, structure, and application in organic synthesis

This comprehensive review discusses the synthesis, structure, and application of the Hendrickson 'POP' reagent and its analogues in organic synthesis. Specifically, the review describes applications of the preceding dehydrating agents in functional group interconversions, heterocycle synthesis, and total synthesis of natural products. Many examples are provided from the literature to show the scope and selectivity (regio and chemo) in these transformations.
