Oligonucleotides containing enantiomeric carbocyclic oxetanocins possessing adenine, thymine, guanine and cytosine were synthesized from an optically active cyclobutane derivative. Their hybridization properties with the complementary oligonucleotides were studied using melting point method, CD spectroscopy, and mixing curve method (Job plots). The artificial nucleotides possessing adenine, guanine and cytosine bases show tendency to form complexes more strongly with ribonucleotide than deoxyribonucleotide. These complexes are triplexes consisting of purine and pyrimidine in 1:2 ratio. Such triplex formation is observed both under high (1 M NaCl) and low salt conditions (0.1 M NaCl).

Carbocyclic (-)-3',5'-di-O-acyloxetanocin A and T were hydrolysed by lipase MY to give the corresponding carbocyclic (-)-3'-O-acyloxetanocins with high regioselectivity. Carbocyclic (±)-3',5'-di-O-acetyloxetanocin A was deacetylated by lipase MY to form t

Adenosine deaminase and lipases catalyzed hydrolysis under high pressure were described. The hydrolysis by both enzymes was facilitated by high pressures. This technique was used for the kinetical resolution of racemic highly modified nucleosides having biological activities.
