Cyclic Phosphorylation Reaction of Diols with Tri(1-imidazolyl)phosphine

Article abstract of DOI:10.1246/bcsj.56.3483

Tri(1-imidazolyl)phosphine (1) gave the cyclic phosphite quantitatively in the reactions with the diols possessing favorably placed hydroxyl groups in which the distance between the two oxygen atoms is 2.7-3.0 Angstroem.The both five- and six-membered cyclic phosphites were obtained quantitatively from the reactions of the diols possessing flexible chains with 1.The course of the selective formation of ribonucleoside 2',3'-cyclic 1-imidazolylphosphonite was interpretated by the higher reactivity of 1 toward the 2'- or 3'-hydroxyl group than toward the 5'-hydroxyl group of ribonucleoside.
