Abstract

The acetoxy-protected maltosyl radical 1, obtained through bromine abstraction from acetobromomaltose (ABM), was studied by means of EPR spectroscopy. At room temperature, only the spectrum of 1 was observed, but at higher temperatures a second radical, the acetoxy-protected 2-deoxymaltos-2-yl radical 2, was detected, resulting from migration of an acetoxy group from position 2 to position 1. Some acetoxy-protected ...
