Ad. Jones et Dw. Knight, A NEW, HIGHLY STEREOSELECTIVE APPROACH TO PYRROLIDINES VIA OVERALL 5-ENDO-TRIG CYCLIZATIONS OF HOMOALLYLIC TOSYLAMIDES, Chemical communications, (8), 1996, pp. 915-916
Iodocyclisations of E-homoallylic tosylamides 7 lead to excellent yiel
ds of either 2,5-trans- or 2,5-cis-3-iodopyrrolidines (10 or 11), depe
nding upon the reaction conditions.
