Functionalization of alcohols as 2-alkoxy N,N′-diphenyl-1,3,2-diazaphospholanes affords highly crystalline derivatives useful for characterization purposes. These tervalent phosphorus derivatives undergo facile and mild conversion into the corresponding alkyl halides with inversion of configuration.

The title compounds were prepared from the peracetylated methyl esters of 4-epi-Neu5Ac2en (14), KDN2en (19) and 4-epi-KDN2en (20), in four steps starting from Neu5Ac and KDN, respectively.
