摘要: Abstract Thiones 2 (′), 4 (′) and 3 are readily prepared from title compounds. Bis-olefinations of with Akiba's reagents W or H afford 8 which can cyclize into 9 upon acid areatment. ( i -PrO) P mediated coupling 5′ affords 7 whose formolysis in 10 bis-olefination yields target compound 1 . The π-donor ability stability discussed.
