Synthesis of Functionalized Deuterioallylic Compounds
摘要:
Functionalized deuterioallylic compounds were efficiently prepared by reaction of the corresponding propargylic derivative with the Schwartz reagent followed by hydrolysis of the adduct with D2O. The Z-3-deuterio-2-propenylstannane, prepared in pure form for the first time, is a useful reagent for the preparation of deuterioallylic compounds which cannot be synthesized by hydrozirconation of the corresponding derivatives.

Using methyl (o-carboran-1-ylmethyl)phosphonate 6 as a novel and versatile borophosphonylating agent, 5'-O-(monomethoxytrityl)thymidine 3'-O-[methyl (o-carboran-1-ylmethyl)phosphonate] (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.
