Efficient synthesis of 1-tetralones from 4-arylbutyric acids by combined use of solid acid catalysts and microwave irradiation

Solid acid catalysts such as H-Beta zeolites effectively promote dehydrative intramolecular cyclization of 4-arylbutyric acids under microwave irradiation to give 1-tetralone derivatives in high yields. Copyright

Chemoselective Oxidation of Equatorial Alcohols with N-Ligated λ3-Iodanes

The site-selective and chemoselective functionalization of alcohols in complex polyols remains a formidable synthetic challenge. Whereas significant advancements have been made in selective derivatization at the oxygen center, chemoselective oxidation to the corresponding carbonyls is less developed. In cyclic systems, whereas the selective oxidation of axial alcohols is well known, a complementary equatorial selective process has not yet been reported. Herein we report the utility of nitrogen-ligated (bis)cationic λ3-iodanes (N-HVIs) for alcohol oxidation and their unprecedented levels of selectivity for the oxidation of equatorial over axial alcohols. The conditions are mild, and the simple pyridine-ligated reagent (Py-HVI) is readily synthesized from commercial PhI(OAc)2 and can be either isolated or generated in situ. Conformational selectivity is demonstrated in both flexible 1,2-substituted cyclohexanols and rigid polyol scaffolds, providing chemists with a novel tool for chemoselective oxidation.
