The Effect of Lithium Ion on the Regioselectivity of Substitution Reactions of Zinc Sulfolenylate
Chou, Ta-Shue,Chang, Chin-Jyh
, p. 529 - 533 (1998)
The addition of lithium cation to zinc sulfolenylates significantly changes the regioselectivity of its reaction toward carbonyl electrophiles. The more lithium salt is added, the more the reactions prefer to take place at the α-position of the sulfolenyl
Regioselective Synthesis of 3-Acylated 2,5-Dihydrothiophene S,S-Dioxides via Ultrasound-promoted Allylzincation of 3-Bromo-2,3-dihydrothiophene S,S-Dioxide

3-Acylated 2,5-dihydrothiophene S,S-dioxides were synthesized from 3-hydroxyalkylated 2,3-dihydrothiophene S,S-dioxides, prepared highly regioselectively via ultrasound-promoted allylzincation of 3-bromo-2,3-dihydrothiophene S,S-dioxide.
