An efficient gold-catalyzed procedure to synthesize 2-alkylidene-3,4-dihydro-2H-1,4-benzoxazines has been developed starting from 2-alkynyl-substituted phenols. This is an intramolecular hydroalkoxylation reaction on alkynes tethered to a phenol moiety that represents a valuable alternative to the already reported transition-metal-catalyzed procedures.
以 2-炔基取代的苯酚为起点,开发出了一种合成 2-亚烷基-3,4-二氢-2H-1,4-苯并噁嗪的高效金催化步骤。这是一种以苯酚为基团的炔烃的分子内氢烷氧基化反应,是已报道的过渡金属催化程序的重要替代品。
