A series of phosphorodichloridites has been prepared incorporating the most commonly used phosphate protecting groups in oligonucleotide synthesis.The groups incude trichloroethyl, tribromoethyl, cyanoethyl, benzyl, methyl, p-chlorophenyl, and nitrophenetyl.The trichloroethyl and the nitrophenethyl appear to be the most stable groups while the cyanoethyl and methyl offer specific advantages.The benzyl and p-chlorophenyl groups are subject to limitations on their utility.Condensations can be carried out in a range of solvents incuding THF, pyridine, and DMF and at temperatures from -78 deg C to 20 deg C with a slight drop in yield with increasing temperature, at least for dinucleotide condensations.
