Article abstract of DOI:10.1002/hlca.19850680127

Using the readily accessible chiral auxiliaries 1-3 the sulfonamide-shielded O-silylated esters 5 underwent ?-face-selective α-acetoxylation on successive treatment with Pb(OAc)4 and NEt3*HF to give after recrystallization α-acetoxy ester 6 in 55-66percen
