A general strategy involving the zincation of 4-bromo-3-chloro-2-sulfolene, in situ condensation with an α-heterosubstituted acetaldehyde, and subsequent cyclization reaction as the key steps toward the synthesis of furano- and thieno-3-sulfolenes is desc
SYNTHESIS OF FURAN-FUSED 3-SULFOLENE. A STABLE PRECURSOR TO FURAN ANALOGUE OF o-QUINODIMETHANE
Chou, Ta-shue,Tsai, Chung-Ying
, p. 663 - 666 (2007/10/02)
Ultrasound-promoted zincation of 2-chloro-4-bromo-2-sulfolene (10) with benzoyloxyacetaldehyde (6), followed by base-induced hydrolysis, intramolecular conjugate addition and aromatization, gives the 3-sulfolene (4) which is a stable precursor to the fura
