Oxiranylmethyl radical

As discussed previously, radical ring-opening reactions of three-membered systems via cyclopropylmethyl and oxiranylmethyl radicals represent a fruitful method in organic synthesis [111]. De Kimpe and coworkers have now shown that azirid-ines can also be used, featuring a radical one-step synthesis of pyrrolizidines 3-280... [Pg.265]

Of course the opening of the lower homologs of 449 is a very fast process. For instance, the opening of the oxiranylmethyl radical to allyloxy radical is a fast process >10 sec (Reference 127). By using a-iodoepoxides as radical probe this permitted the conclusion to be reached that the reductive elimination of a-iodoepoxides to allylic alcohols with sodium naphthalides, as well as the... [Pg.260]
