alkoxides with β-substituted 2-(p-tolylsulfonyl)acetylenes, involving an anti-Michael addition reaction followed by the in situ elimination of the sulfonyl moiety, provides a direct method for the synthesis of alkyl alkynyl ethers bearing aryl or TIPS groups joined to the triple bond. Arylalkynyl ethers derived from primary alkoxides are in situ hydrolyzed into arylacetic esters.
金属醇盐与 β-取代的 2-(对甲苯磺酰基)乙炔反应,包括反迈克尔加成反应,然后原位消除磺酰基部分,为合成带有芳基或芳基的烷基炔基醚提供了一种直接方法。 TIPS 基团加入了三键。衍生自伯醇盐的芳炔基醚原位水解成芳基乙酸酯。
