  2,4-Dinitrophenol as an activating reagent in a facile preparation of cyclic phosphate triesters

  摘要：

  2,4-Dinitrophenol was employed with benzyloxy-bis-(diisopropylamino)phosphine to synthesise the cyclic phosphate derivatives of a series of alkane diols (HO-(CH2)(n)-OH, n= 2-6) in good isolated yields. Tetrazole and DNP were compared by P-31 NMR spectroscopy for their ability to catalyse the cyclisation at the P(III) stage. Investigation of the phosphate triester stability under various oxidation and chromatographic conditions resulted in the optimisation of the isolation procedures of the chemically unstable cyclic compounds. Conditions for debenzylation were developed to yield the corresponding cyclic phosphodiesters quantitatively. The methodology was further applied to the preparation and isolation of the cyclic phosphate derivative of a carbohydrate. (C) 2003 Elsevier Ltd. All rights reserved.

  Thermoresponsive polyphosphoesters bearing acetoxymethyl (AM) groups were newly synthesized. The polymers had the LCST-type cloud point in aqueous media, and the thermoresponsive phenomena was influenced by the condition of the medium. About 40% of the AM groups in the polymers were cleaved in contact with esterase for 24 h in phosphate buffer solution. This was significant compared with the spontaneous cleavage in the buffer solution. After the cleavage of the AM groups, the thermoresponsivity of the polyphosphoesters was diminished.

  新近合成了一种带有乙酰氧甲基（AM）基团的热响应性聚磷酸酯。这类高分子在水中表现出LCST型浊点，其热响应现象受介质条件的影响。在磷酸盐缓冲溶液中，与酯酶接触24小时后，约有40%的AM基团被裂解，这一现象显著区别于在缓冲溶液中的自发裂解。AM基团裂解后，聚磷酸酯的热响应性降低了。
