A facile, efficient synthesis of 3-(guaiazulen-l-yl)succinimides was developed by Michael-type addition of guaiazulene to maleimides in the presence of p-toluenesulfonic acid under mild reaction conditions.
An efficient and mild synthesis of 2-(guaiazulen-l-yl)furans, starting from easily accessible 1-(3-aryl-2- cyanopropenoyl)guaiazulenes, tributylphosphine and acyl chlorides, is described. The strategy employs the ...An efficient and mild synthesis of 2-(guaiazulen-l-yl)furans, starting from easily accessible 1-(3-aryl-2- cyanopropenoyl)guaiazulenes, tributylphosphine and acyl chlorides, is described. The strategy employs the intramolecular Wittig protocol as a key step to append the crucial furan ring, leading to the highly functional furans in good yields.展开更多
