Structure and isomerization of O,O-phenylene penta-coordinated phosphoryl serine
摘要:
A stable penta-coordinated serine-carboxylic-phosphoric anhydride may be synthesized at temperatures below -18degreesC. Above that temperature, the product was shown to isomerize to another penta-coordinated phosphorus compound, which was proven by the change in the magnitude of observed P-C coupling constants. The mechanism for the anhydride to ester isomerization might provide a clue to the proposal of high-energy supply for biochemistry. Organic bases were shown to exert little influence on the rate of isomerization. (C) 2002 Elsevier Science B.V. All rights reserved.
