Abstract: Diastereomers of 2-oxo-2-substituted phenoxy-4-phenyl-5,5-dimethyl-1,3,2-dioxaphosphorin were synthesized. The synthetic methods, solvents and salts appeared to exhibit significant influences on the cis/trans ratio of the products. The isomerization between cis and trans cyclic phosphates was investigated. The preliminary bioassay indicated that some isomers have herbicidal and plant growth activity.

Key words: dioxaphosphorin, stereoselective synthesis, diastereomer, biological activity
