Polymer of phosphonylmethyl-2,4- and -2,6-diamino benzene and polyfunctional monomer [PDF]
, 1986 A phosphonyl methyl benzene is prepared by nitration to produce a 2,4-dinitro phosphonyl methyl benzene, which is then reduced to a diamino compound. The diamino compound is then used to cure a polymerizable monomer.

Efficient routes to epimerically-pure side-chain derivatives of lanosterol [PDF]
, 2004 A technically simple route is described to individual epimers of side-chain derivatives of lanosterol (3-hydroxy-5-lanosta-8,24-diene). Epimerically pure 24,25-epoxy-, 24,25-dihydroxy- and 24-bromo-25-hydroxy-lanosterol have been prepared in good yield ...
