“…and heating to between 60 ˚C and 100 ˚C. Following this procedure, in the C(3')-F series, inclusion of Ph, 4-MeC6H4-, 4-MeOC6H4 and 4-F3CC6H4substituted allylic ethers, as well as 4-Cl, 5-F, 5-NO2, 5-MeO and 6-Cl substituents within the oxindole were tolerated, giving the corresponding [1,2]-Wittig products (46)(47)(48)(49)(50)(51)(52)(53)(54) with good to excellent enantioselectivity (91:9 to 97:3 er). In the C(3')-H series, variation of the aryl substituent within the allylic ether showed that Ph, 4-MeOC6H4, 4-F3CC6H4, 4-FC6H4, 2-MeOC6H4, 1-naphthyl and 2-naphthyl-substitution, heteroaromatic 3thienyl and C(2')-methyl substitution, alongside 4-Cl, 5-OMe and 6-Br substituents within the oxindole were tolerated, allowing the formation of enantioenriched [1,2]-Wittig rearrangement products 45, 55-65 (87:13 to 95:5 er).…”
