A New Method of Introducing SCH3and SCD3Groups to Phosphorothioates
摘要:
A new synthesis of phosphorothioates starting fromphosphites and cyanuric chloride (TCT)-activated DMSO is reported herein. This method enables the incorporation of SCH3 and SCD3 groups into phosphorothioates in good yields. The labeling purities of the products are excellent.

using nucleophilic and electrophilicreagents. The nucleophilic reagent, tetramethylammonium O,O‐dimethyl phosphorothioate, was synthesized in near‐quantitative yield from Me3SiP(O)(OMe)2, elemental sulfur and Me4NF. Its umpolung with N‐bromophthalimide provided the electrophilicreagent, O,O‐dimethyl‐S‐(N‐phthalimido)phosphorothioate. Complementary methods based on these reagents enable the phosphorothiolation

The development of efficient methods for the metathesis and phosphorylation reactions of disulfide compounds is of widespread interest due to their important synthetic utility in polymer, biological, medicinal and agricultural chemistry. Herein, we demonstrate the use of N‐heterocyclic carbenes (NHCs) as versatile organocatalysts to promote these challenging reactions under mild conditions. This metal‐
