topic in organic synthesis due to the disfavored kinetic and thermodynamic features. Herein we detail an efficient intermolecular process using siloxy alkynes as substrates and oxetene ring expansion as the key strategy. With extension to a new silyl-masked alkyne, this reaction now features a broad scope, high efficiency, and mild conditions.
由于不利的动力学和热力学特征,中环内酯的合成仍然是有机合成中的挑战性课题。在本文中,我们详细介绍了一种有效的分子间过程,该过程使用甲硅烷氧基炔烃作为底物,以氧杂环丁烷环扩环为关键策略。通过扩展到新的甲硅烷基掩盖的炔烃,该反应现在具有广泛的范围,高效和温和的条件。
