摘要：
The reaction of 4,5-dihydro-4,4-bis(trifluoromethyl)-2-phenyl-6,7-(4-chlorobenzo)[e]-1,3,2-dioxaphosphepin-5-one with chloral (1:2) proceeds with evolving hexafluoroacetone and gives spiro{2-oxo-4-trichloromethyl-4,5-dihydro-2-phenyl-6,7-(4-chlorobenzo)[f]-1,3,2-dioxaphosphepine-5,2'-(3-trichloromethyl)oxirane) with a high stereoselectivity. Configuration of the four chiral centres (p(S)(2)C(S)(4)C(S)(5)C(S)5C(S)(3)'/(PRCRCRCR3)-C-2-C-4-C-5') was determined by a single crystal X-ray diffraction.
