    摘要: The present invention discloses methods for the synthesis of oligonuclelotidesa and nucleoside phosphoramidites. The methods are based on employing aryl-substituted 5-phenyl-lH-tetrazoles with perfluroalkyl groups on the aromatic ring as activators. In one aspect the activators are used in the synthesis of oligonucleoties via the phosphoramidite approach. In this aspect the activators are highly efficient and can be applied with very short coupling times. In a further aspect, the activators of the invention are used in the synthesis of phosphoramidites through the reaction of nucleosides comprising a free hydroxyl group with phosphitylating agents. This aspect of the activators provide very pure phosphoramidites under mild conditions. The activators of the invention are further characterized as being highly soluble, non-hygroscopic and non-hazardous.
