报道了一种利用简单易得的底物, 通过酸促进的缩合环化反应来合成2,3-二氢苯并[d][1,3]氧杂磷杂环戊烯类化合物的新路线. 该反应操作简便, 通过普通硅胶色谱即可实现反应中产生的非对映异构体的分离, 可应用于克级规模合成. 当改用联萘酚磷酸酯[(±)-BINOL-phosphoric acids]为缩合反应促进剂时, 可以实现高非对映立体选择性的构筑苯并氧杂磷杂环戊烯类化合物.

A facile method to synthesize dihydrobenzooxaphospholes was developed from a p-toluenesulfonic acid (p-TSA)- promoted intermolecular cyclocondensation of the readily available 2-phosphinylphenol and aromatic aldehydes. The desired products were obtained as a mixture of stereoisomers. Interestingly, the diastereoisomers could be separated easily by flash column chromatography. The gram-scale and diastereoselective syntheses were also successfully performed.

Key words: organophosphorus, dihydrobenzooxaphosphole, cyclocondensation, diastereoselectivity
