A new, facile, and protection-free one-pot chemical synthesis of 2′-deoxynucleoside-5′-tetraphosphates
摘要:
A new straight forward, reliable, and an efficient method for the chemical synthesis of 2'-deoxynucleoside-5'-tetraphosphate is reported. The present 'one-pot, three step' synthetic strategy involves the monophosphorylation of nucleoside followed by reaction with tris-(tri-n-butylammonium) triphosphate and hydrolysis of the putative cyclic tetrametaphosphate intermediate to provide the corresponding 2'-deoxynucleoside-5'-tetraphosphate in moderate yield with high purity.

An efficient chemical synthesis of pyrimidine specific 2′-deoxynucleoside-5′-tetraphosphates, such as 2′-deoxycytidine-5′-tetraphosphate (dC4P) and thymidine-5′-tetraphosphate (T4P) is described. The present three-step synthetic strategy involves monophosphorylation of 2′-deoxynucleoside using phosphorous oxychloride, conversion of 5′-monophosphate into the corresponding imidazolide salt, followed
The present invention provides a novel sequencing apparatus and the methods employed to determine the nucleotide sequence of many single nucleic acid molecules simultaneously, in parallel. The methods and apparatus of the present invention offer a rapid, cost effective, high through-put method by which nucleic acid molecules from any source can be readily sequenced without the need for prior amplification of the sample or prior knowledge of any sequence information.
