Synthesis and Stereochemistry of New Cyclic Phosphate-phosphonates
摘要:
The novel cyclic phosphate-phosphonates,cis/trans-2-phosphonobenzyloxy-4-aryl-5,5-dimethyl-1,3,2-dioxaphosphorinane 2-sulfides(selenides) (7a-f),were synthesized by a one-pot reaction using tris(diethylamino) phosphine activated by iodine as the phosphorylating and ring-closing reagent in good overall yields.The geometric stereoisomers were isolated and characterized.A cis-configuration and a chair preferred conformation of one isomer of 7b were established by X-ray diffraction analysis.
