Cycloaddition of enamines with alkynylphosphonates. A route to functionalized medium sized rings
Ruder, Suzanne M.,Norwood, Bradley K.
, p. 3473 - 3476 (1994)
Substituted seven and eight membered rings were formed from cyclopentanone and cyclohexanone via cycloadditions of pyrrolidine enamines with alkynyl phosphonates. This procedure provides straightforward access to functionalized medium sized rings that could be further manipulated in the synthesis of a number of natural products.
One-pot synthesis of 1-alkynylphosphonates
Gil, Jun Mo,Sung, Jin Wuk,Park, Chan Pil,Oh, Dong Young
, p. 3171 - 3174 (1997)
1-Alkynylphosphonates 3 are prepared in a one-pot procedure from diethyl phosphorochloridates 2 and alkynyllithiums 1, which are readily generated by the reaction of 1-alkynes with n-BuLi.
Enantioselective Synthesis of Chiral Phosphonates via Rh/f-spiroPhos Catalyzed Asymmetric Hydrogenation of β,β-Disubstituted Unsaturated Phosphonates

The first asymmetric hydrogenation of β,β-diaryl unsaturated phosphonates has been realized for synthesis of β,β-diaryl chiral phosphonates with excellent enantioselectivities (up to 99.9% ee) catalyzed by the Rh-(R,R)-f-spiroPhos complex. Furthermore, this catalyst also exhibits comparably excellent performance for β-aryl-β-alkyl unsaturated phosphonates providing the corresponding chiral phosphonates with up to 99.9% ee values. This methodology provides a straightforward access to asymmetric synthesis of chiral phosphonates.
Synthesis of 1,2,3-triazolyl-5-diethylphosphonate by domino reaction
Tripolszky, Anna,Tóth, Emese,Bálint, Erika
, p. 377 - 378 (2019/01/04)
The synthesis of 1,2,3-triazolyl-5-diethylphosphonate was studied by the domino reaction of benzyl azide, phenylacetylene and diethyl phosphite. The effect of the reaction stoichiometry, the atmosphere and the amount of the catalyst were investigated.
