Iodonium nitrate

The work of Lown and coworkers122 on iodonium nitrates has been reviewed.1 Addition of these reagents proceeds in a trans stereospecific manner, but with mediocre regiospecificity. The Lown group has also studied BrNC>3 and found it to be a more regiospecific reagent.123... [Pg.350]

Significant amounts of the bicyclo[3.3.1]nonane adduct and of the octahydropental-enes were isolated also from the reaction of 3 with preformed iodine acetate and iodine acetate thallium (equation VS) whereas only the monocyclic 1,2-adducts were obtained from treatment of 3 with iodine azide, iodine isocyanate or iodine nitrate . The different propensity to give transannular products with these latter reagents has been related to the different positive charge density on carbons in the corresponding iodonium ion intermediates. [Pg.591]

Pummerer-like cyclization reactions were utilized to prepare spirocyclic oxindole derivatives <04OL1869, 04OL2849>. For example, treatment of 2-sulfenylindole 215 with an iodonium reagent in the presence of 2,6-lutidine produced thioimidate 216. Oxidation of the latter with cerium ammonium nitrate (CAN) gave spirooxindole 217. [Pg.133]
