Using methyl (o-carboran-1-ylmethyl)phosphonate 6 as a novel and versatile borophosphonylating agent, 5'-O-(monomethoxytrityl)thymidine 3'-O- (8) and thymidine(3',5')thymidine (o-carboran-1-ylmethyl)phosphonate (12) were synthesized.The internucleotide (o-carboran-1-ylmethyl)phosphonate linkage was resistant to cleavage by phosphorodiesterases.The dinucleotide 12 represents a new class of modified lipophilic oligonucleotide-bearing carboranyl residue, designed as a carrier for boron neutron capture therapy and for potential use in antisense oligonucleotide technology.

An alternative approach is reported for the synthesis of methyl ester protected bisphosphonate building blocks, such as methylene bisphosphonate, vinylidenebisphosphonate and aryl substituted prochiral vinylidenebisphosphonates, that cannot be obtained directly from dimethyl phosphite and dichloromethane.

Paragraph 0030-0038, (2020/07/24)
The invention discloses a preparation method of a cyclic phosphonate flame retardant, which relates to the technical field of organic phosphorus flame retardant synthesis. The method comprises the following steps of taking trimethylolpropane and trimethyl phosphite as raw materials with the feed mole ratio of 1: 2-4, selecting methyl benzenesulfonate or methyl p-toluenesulfonate as a catalyst, controlling proper process parameters such as catalyst quantity, temperature, time and the like, and carrying out transesterification and rearrangement reaction to obtain the phosphonate flame retardantwith a cyclic structure and the byproduct dimethyl methylphosphonate flame retardant. The method provided by the invention has the advantages of few raw material varieties, easy source, low cost, rapid reaction, high efficiency, environment-friendly process, energy conservation and consumption reduction; the product prepared by the method is the same as the product prepared by the existing method,but the production period is shortened by 2/3-3/4, the production capacity is greatly improved, and the method is suitable for industrial production.
