White Crystalline Solid | [Uses]
2-Chloro-1,3,2-benzodioxaphosphorin-4-one is used as a reagent:
- In the phosphorylation and phosphitylation of alcohols.
- In the formation of H-phosphonates which are commonly utilized in the synthesis of nucleotides.
- To synthesize nucleoside triphosphates by treating with acyl protected nucleoside.
| [Uses]
2-Chloro-4H-1,3,2-benzodioxaphosphorin-4-one is a reagent used in phosphorylation and phosphitylation of alcohols and in the formation of H-phosphonates. It is also reactive cyclic phosphitylating reagent involved in fast coupling rates and hydrolytic cleavage more readily compare to that of a acyclic analog. | [Uses]
Highly reactive cyclic phosphitylating reagent which provides fast coupling rates, and hydrolytic cleavage occurs more readily than with acyclic analogs |
