Collina

In the context of preparing analogues of chiral l,2-dimethyl-3-(2-naphthyl)-3-hy-droxy-pyrrolidines, which are known non-peptide antinociceptive agents, Collina and coworkers have reported the solvent-free dehydration of hydroxypyrrolidines to pyrrolines under microwave conditions (Scheme 6.141) [278]. In a typical experiment, the substrate was adsorbed onto a large excess of anhydrous ferric(III) chloride on silica gel and then irradiated as a powder under microwave conditions for 30 min at 150 °C. The microwave method leads to dehydration without racemiza-tion and provides higher yields in considerably shorter times than the conventionally heated process.
