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.
METHOD FOR PRODUCING ORGANOPHOSPHORUS COMPOUND

Paragraph 0045; 0079, (2020/05/02)
PROBLEM TO BE SOLVED: To provide a method for producing an organophosphorus compound which has excellent energy efficiency without containing a halogenated alkyl or a by-product derived from a halogenated alkyl. SOLUTION: There is provided a method for producing an organophosphorus compound by reacting a trivalent organophosphorus compound represented by the following general formula (1) in the presence of a super strong acid and/or at least one acid catalyst containing a solid superstrong acid catalyst to generate a pentavalent organophosphorus compound represented by the following general formula. (where Z1 represents OR2 or R2; Z2 represents OR3 or R3; R1, R2 and R3 represent an alkyl group, an alkenyl group or the like; when R2 and R3 are an alkyl group or the like, R2 and R3 may be bonded to each other to form a cyclic structure; and R1 may be a hydrogen atom.)
