Synthesis of polyamino-2'deoxynucleosides was studied. A synthesis of 2'-deoxyadenosine and 2'-deoxyguanosine derivatives carrying a protected spermine moiety at N-6 and N-2 positions respectively is described using unprotected polyamines as substrates. T
Nucleotides: Part LXI: Phthaloyl strategy: A new concept of oligonucleotide synthesis
Beier, Markus,Pfleiderer, Wolfgang
, p. 633 - 644 (2007/10/03)
A new alternative strategy of oligonucleotide synthesis was developed by use of the phthaloyl protecting group for the exocyclic amino functions of the nucleobases (see 9-12). This approach combines the advantages of cheap and easily accessible monomeric building blocks (see 17- 20), standard machine-aided oligonucleotide synthesis, and a fast deprotection protocol which is orthogonal to the cleavage procedure from the solid support. The crude oligonucleotides show high purity and require, in general, no further chromatographic purification.

THE p-NITROPHENYLETHYL (NPE) GROUP. A VERSATILE NEW BLOCKING GROUP FOR PHOSPHATE AND AGLYCONE PROTECTION IN NUCLEOSIDES AND NUCLEOTIDES
Himmelsbach, Frank,Schulz, Bernd S.,Trichtinger, Thomas,Charubala, Ramamurthy,Pfleiderer, Wolfgang
, p. 59 - 72 (2007/10/02)
The syntheses of new monomeric building blocks for oligonucleotide synthesis via the phosphotriester approach containing the p-nitrophenylethyl group for phosphate and aglycone protection are described.Blocking of the amide function in guanosines at O6 can be achieved by the Mitsunobu reaction forming the corresponding O6-p-nitrophenylethyl derivatives (4,5,10).Sugar-protected thymidine (16) and uridine (17) have been alkylated at O4 in an SN1-type reaction by p-nitrophenylethyl iodide-silver carbonate in benzene to form the O4-p-nitrophenylethyl derivatives (18,19).Protection of the amino group in 2'-deoxycytidine (25) and cytidine (26) can be performed directly by 1-(p-nitrophenylethoxycarbonyl)-benzotriazole in DMF to obtain the corresponding carbamates (27,28) as a new type of N4-acylated cytidine derivative. p-Nitrophenylethoxycarbonylation of the amino group in 2'-deoxyadenosine (33) and adenosine (34) requires previous sugar protection by acyl or silyl groups and can then be achieved by p-nitrophenylethyl chloroformate or better by 1-methyl-3-p-nitrophenylethoxycarbonylimidazolium chloride to form N6-p-nitrophenylethoxycarbonyladenosines (38,39,40,42).The various p-nitrophenylethyl blocking groups are stable under mild hydrolytic conditions (e.g. ammonia and triethylamine) but can be cleaved selectively by DBU or DBN in aprotic solvents. 5'-O-Monomethoxytritylation (12,29,43) as well as phosphorylations at the 3'-OH group can be effected to give the corresponding 3'-(2,5-dichlorophenyl,p-nitrophenylethyl)-phosphotriesters (13,22,30,44) also in high yields.Oximate cleavage of the latter compounds to the phosphodiesters (14,24,32,46) and detritylation to the 5'-unblocked phosphotriesters (15,23,31,45) do not affect the aglycone protecting groups, thereby demonstrating their general versatility.The newly synthesized compounds have been characterized on the basis of their elementary analyses (C,N,H), and UV- and 1H-HMR-spectra.
SYNTHESIS OF O6-p-NITROPHENYLETHYL GUANOSINE AND 2'-DEOXYGUANOSINE DERIVATIVES
