权利人:ROCHE DIAGNOSTICS GMBH
摘要:The invention relates to a new diastereoselective synthesis method for highly modified nucleoside triphosphates with two conjugable groups. The method works in liquid phase with conventional laboratory equipment as used in any chemical laboratory or production. For this, a new chiral P(V) phosphorylation reagent has been designed that allows highly efficient diastereoselective synthesis under mild conditions. Overall, a highly efficient, diastereoselective, high quality, cost-effective synthetic method of modified nucleoside triphosphates has been developed.
