Synthesis of DNA using a new two-step cycle

Abstract

For the first time a new, two-step method is described for synthesizing deoxyribonucleic acid. The approach uses 5'-carbonate protected 2'-deoxynucleoside-3'-phosphoramidites as synthons and a peroxy anion buffer that removes the carbonate protecting group and oxidizes the internucleotide linkage. Following synthesis via this two-step cycle, oligomers are isolated by standard procedures.
