Abstract

As a versatile building block, 3, 4-bis (trimethylsilyl) furan (l), conveniently obtained through a Diels-Alder reaction between 4-phenyloxazole and bisttrimethylsilyl) acetylene, was able to undergo Diels-Alder cycloadditions with dienophiles. In two separate experiments, extrusion of bis (trimethylsily1)-acetylene occurred when 1 was treated with acetylenic dienophiles. Furan 1 was also found to undergo Friedel-Crafts acylations at the ...
