Calculate Digit Verification of CAS Registry Number 130888-75:
(8*1)+(7*3)+(6*0)+(5*8)+(4*8)+(3*8)+(2*7)+(1*5)=144
144 % 10 = 4

1,3-Dipolar Cycloaddition of Diethyl Nitromethylphosphonate, via the Nitrile Oxide, to Alkenes and 1-Alkynes. A Convenient One-Pot Synthesis of 3-Diethoxyphosphoryl-4,5-dihydroisoxazoles and 3-Diethoxyphosphorylisoxazoles

Zhang, Rongyu,Chen, Jian

, p. 817 - 819 (2007/10/02)

The one-pot reaction of diethyl nitromethylphosphonate with alkenes or 1-alkynes in the presence of phosphoryl chloride and triethylamine leads to 3-diethoxyphosphoryl-substituted 4,5-dihydroisoxazoles or isoxazoles, respectively, in good yields.
