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
