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

3--3-sulfolenes (5) were conveniently synthesized by a sequence of mesylation, elimination, and Michael addition reactions of 4-hydroxyalkylated 2-sulfolenes (2), which were prepared regioselectively via ultrasound-promoted allylzincation of 4-bromo-2-sulfolene (1). 3-Alkyl-3-sulfolenes were synthesized from desulfurization of 5.The application of the sequence was exemplified with the simple synthesis of α-myrcene.
Regioselective Synthesis of 3-Acylated 2,5-Dihydrothiophene S,S-Dioxides via Ultrasound-promoted Allylzincation of 3-Bromo-2,3-dihydrothiophene S,S-Dioxide

, p. 1552 - 1553 (2007/10/02)
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.
