- 中文摘要: A general strategy involving the zincation of 4-bromo- 3-chloro-2-sulfolene, in situ condensation with an .alpha.- heterosubstituted acetaldehyde, and subsequent cyclization reaction as the key steps toward the synthesis of furano- and thieno-3- sulfolenes is described. These fused-3- sulfolenes are demonstrated to be good precursors for the corresponding o-quinodimethanes.
