Oxidizing polymers: A polymer-supported, recyclable hypervalent iodine(V) reagent for the efficient conversion of alcohols, carbonyl compounds, and unsaturated carbamates in solution

The oxidation of various alcohols and cyclization of an olefinic carbamate succeeds with the first polymer-supported iodine(v) reagent (see scheme). The novel oxidizing polymer oxidizes sensitive and complex alcohols, including protected amino alcohols, efficiency in good excellent yields. In addition, the α,β-dehydration of a ketone is demonstrated.

FRAGMENTATION OF ISOPULEGOL BY A RADICAL PROCESS

The reaction of isopulegol with sulfuryl chloride leads in certain conditions to a mixture of 8-chloro citronellal and 6-chloro isocitronellal.The radical character of this fragmentation is supported by the result of two reactions known to proceed via an alkoxy radical.
