Novel oligonucleotide dimers containing hydroxamate linkages (15 and 16) were synthesized, incorporated into oligonucleotide sequences and studied for their hybridization properties with complementary DNA and RNA targets. The modified oligonucleotides showed similar binding properties and enhanced resistance to exonucleases compared to natural oligonucleotides. (C) 2000 Elsevier Science Ltd.
114. Aza-claisen rearrangement: Synthesis of 5'-branched 5'- aminothymidines

The syntheses of both diastereoisomers of 5'-ethyl-substituted thymidine dimers, the (5'R)- and (5'S)-configurated 33a and 33b, respectively, in which the natural phosphodiester linkage is replaced by an amide group (C(3')- CH2CONH-CH(5')(Et)), are described. Their fully protected derivatives 35a and 35b, respectively, are suitable for incorporation into antisense oligonucleotides. Unexpectedly, an attempted Pd(II)-catalysed aza-Claisen rearrangement of trichloroacetimidate 7 provided the diastereoisomerically pure cyclopropane derivative 17, whose structure was confirmed by X-ray analysis.
