Highly stereoselective synthesis of (2'R)-[2'-2H]-2'-deoxyribonucleosides (2'R:2'S = > 99:1) were accomplished by treating 2'-bromo-3',5'-O-TPDS-2'-deoxyribonucleosides with tributyltin deuteride at lower temperatures such as -60 degrees C in the presence of triethylborane. Moreover, synthesis of some oligodeoxyribonucleosides involving them will be described.

Homoallylation of aldehydes with isoprene and triethylborane catalyzed by Ni(acac)(2) gave hydroxyalkenes in good yield with excellent regio- and stereoselectivity. Cross metathesis of the hydroxyalkenes with methyl acrylate using second-generation Grubbs catalyst and copper(I) iodide afforded alpha,beta-unsaturated esters, which underwent
