Chamberlin, A. Richard,Chung, John Y. L.
, p. 4425 - 4431 (1985)
The enantioselective synthesis of seven pyrrolizidine diols has been accomplished from a single, readily available intermediate.The key step of this general scheme involves an acetoxy-directed acyliminium ion-ketene dithioacetal cationic cyclization to gi
