A mixture of the four stereoisomers of 1,7-dimethylnonyl propanoate, the female sex pheromone of the western corn rootworm (Diabrotica virgifera virgifera LeConte), was synthesized in four different ways by employing one of the following four reactions as the key step:

The reaction of 1-(2,3-anhydro-5-O-trityl-beta-D-lyxofuranosyl)-2-O-methyluracil (1a) and its thymine analogue (1b) with dilithium tetrahalocuprate (Li2CuX4) revealed excellent to perfect regioselectivity, yielding 2,2'-anhydro-3'-halonucleosides (2a-d), while the same reactions with 2,3-anhydro uracil and thymine nucleosides (4a,b) gave arabinosyl (5a-d) and xylosyl halohydrins (6a-d)
