开发了一种炔酯的对映选择性分子内环化反应,该反应采用由手性席夫碱和 t-BuOK 原位生成的布朗斯台德碱催化剂。该反应是在布朗斯台德碱催化下,简单的酯烯醇化物与炔烃进行对映选择性分子内加成的罕见例子。
An enantioselective intramolecular cyclization reaction of alkynyl esters was developed, which employs a Brønsted base catalyst generated in situ from a chiral Schiff base and t-BuOK. This reaction is a rare example of the enantioselective intramolecular addition of simple ester enolates to alkynes under Brønsted base catalysis.
