α-Sulfonyl and α-sulfinyl radicals can be generated from the corresponding α-halosulfones and α-halosulfoxides. Our results indicate that these radicals cyclize very efficiently.
DIASTEREOSELECTIVITY IN THE CYCLIZATION OF 1-(2-(BENZYLOXYMETHYL)-3-BUTENYL)-5-ETHOXY-2-PYRROLIDINONES
Zonjee, Johannes N.,Koning, Henk de,Speckamp, W. Nico
, p. 7553 - 7564 (2007/10/02)
1-(2-(Benzyloxymethyl)-3-butenyl)-5-ethoxy-2-pyrrolidinones 12 cyclize upon formic acid treatment to indolizinones.The effect of some substituents α to the iminium carbon atom on the diastereoselectivity of the cyclization is discussed.
