Abstract
In this paper, a new simple method was used in the preparation of 1-oxo-1-phospha-2,6, 7-trioxabicyclo [2. 2. 2]-4-chloromethyl octane (4), and new derivatives of bicyclic phos-phate (5a~f, 7, 8a~i), which are 4-methylene sulfide, 4-chloroethanethioyl carbonyl,4-(β-thioalkyl)-α-thioic ester, respectively, were synthesized by the reaction of (4) or1-oxo-1-phospha-2, 6, 7-trioxabicyclo [2. 2. 2]-4-chlorocarbonyl octane (3) with mercaptans.The corresponding sulfoxides (6a~f) were also obtained by further oxidation of 5a~f.All the compounds were confirmed by elemental analysis, IR and 1~H NMR.
