SYNTHESIS AND REACTIVITY OF DENDRIMERS BASed ON PHOSPHORYL (P=O) GROUPS
摘要:
The synthesis of phosphoryl-based dendrimers is described, using the reiteration of a two-steps process which gives alternatively aldehyde and P(O)Cl-2 end groups. The synthesis has been carried out up to the third generation, to give a compound which bears 24 chlorine atoms on the surface. Preliminary experiments on the first generation of the dendrimer possessing either 6 CHO or 6 Cl groups show that these compounds display a versatile reactivity. For instance, alpha, beta-unsaturated esters, crown ethers, chiral phosphine sulfides or diallylamine are grafted on the surface, and the resulting dendrimers are isolated in good to nearly quantitative yields.

triple-equivalent supports in liquid-phase peptide synthesis (LPPS). Through the support-aided precipitation effect of TFP derivatives, the peptide intermediates during peptide synthesis were separated and collected via rapid precipitation and facile filtration without chromatographic purification. Furthermore, the TFP derivative support can be directly recycled for reuse without further regeneration after

The cavity of a [2+3] organic molecular cage was partitioned and functionalized by inserting inner-directed PO bonds, which shows CO2 capture and CH4 exclusion due to the size-matching and polarity effects.
Abstract Two ways of synthesis of phosphorus dendrimers are elaborated up to the twelfth generation for one of them, to give a molecule which possesses 12288 functions. Examples of the reactivity of some dendrimers are described.
