The resolution by entrainment which allows the pure enantiomers to be obtained by direct crystallization of the racemate is possible only when the racemate is a conglomerate (eutectic mixture).Spontaneous resolutions exist to an extent less than 10percent

Magnetic nanoparticle Fe3O4-immobilized guanidine (MNPs-Guanidine) as a novel magnetically interphase nanocatalyst was synthesized and characterized. MNPs-Guanidine catalyzed the synthesis of α-hydroxyphosphonates from aldehydes and
5-Fluorouracil derivatives containing α-hydroxy phosphonates

In order to find high acitivity and low toxicity antitumor drug-lead compounds, 13 novel N1-(2-furanidyl)-N3-(O,O- dialkylphosphonyl aryl (alkyl)methoxy-carbonylmethyl)-5-fluorouracils were synthesized via phase-transferred catalytic reactions of chloroacetyloxyalkyl phosphonates 2 with N1-(2-furanidyl)-5-fluorouracil. The structures of the products were confirmed by 1H NMR, 31P NMR, IR, and MS spectra and elemental analyses. The results of preliminary bioassay showed that the new compounds possess some extent of inhibitory effect against HCT-8 and Bel-7402 cell lines and good fungicidal activities.

To investigate the influence of a fluorine moiety on the biological activity of phenoxyacetoxyalkylphosphonates, a series of fluorine-containing phenoxyacetoxyalkylphosphonates were synthesized and screened for herbicidal activity in a greenhouse. The majority of the title compounds showed better preemergence activity than postemergence activity against the test plants, especially on monocotyledon. Compound 5l exhibited notable activity. Results showed that by introducing a fluorine moiety to the parent structure of phenoxyacetoxyalkylphosphonates, a series of new compounds with satisfactory herbicidal activity could be synthesized. A reasonable combination of a fluorine moiety and other substituents on the benzene ring had a great influence on the herbicidal activity. Copyright Taylor & Francis Group, LLC.
