, p. 147 - 150 (2007/10/03)
Dithioacetal-S,S-dioxides 6 and 7 undergo cyclisation to give pyrrolidines and piperidines upon exposure to Lewis acid. An unexpected tandem cyclisation of 5 to give 10 is described.
A Facile Allylic 1,3-Rearrangement of a Sulfonyl Group and Its Application to a Synthesis of α,β-Unsaturated Ketones
Ogura, Katsuyuki,Iihama, Teruyuki,Kiuchi, Shigeo,Kajiki, Toshitaka,Koshikawa, Osamu,et al.
, p. 700 - 705 (2007/10/02)
A p-tolylsulfonyl group undergoes a SiO2-catalyzed 1,3-rearrangement in a sulfenylated allylic system and this rearrangement can be utylized in novel and convenient syntheses of α,β-unsaturated ketones 6 using 3-(methylthio)-2-propenyl p-tolyl sulfone (1)
