| | Di-tert-butyl Chloromethyl Phosphate Usage And Synthesis |
| Description |
Di-tert-butyl (chloromethyl) phosphate has become one of the most common reagents to prepare phosphon-oxymethyl pro-drugs, generally by direct alkylation of hydroxyl or amino groups. Its synthesis was first reported in 1999 via a reaction of di-tert-butyl tetramethylammonium phosphate with chloroiodomethane. This approach required the use of the corresponding tetramethylammonium phosphate and a vast excess (>11 equiv) of chloroiodomethane to minimize the formation of tetra-tert-butyl methylene bisphosphate[1].
| | Uses | Used as an intermediate for laboratory research. | | Synthesis | Di-tert-butyl (chloromethyl) phosphate, a key compound in the formation of many phosphon-oxymethyl pro-drugs, is prepared by reacting chloromethyl chlorosulfate (CMCS) with di-tert-butyl potassium phosphate (DTBPP) . | | References | [1] Bin Zheng*. “Development of Efficient Processes for the Preparation of Di-tert-butyl Potassium Phosphate and Di-tert-butyl (Chloromethyl) Phosphate.” Organic Process Research & Development 18 5 (2014): 636–642. |
