Reaction Steps

At -78° C., add 1-nitrocyclopentene (1.8 ml, 18.4 mmol) in THF (20 ml) to a THF solution (33 ml) of the zinc-copper reagent prepared from 2-(2-iodoethyl)-1,3-dioxane (5.6 gm, 23 mm), zinc powder (1.58 g), CuCN (1.9 g) and LiCl (1.7 g), according to the general procedure of P. Knochel et. al. (J, Org. Chem. 1989, 54, 5200). After 15 min. warm to 0° C. for one hour, then recool to -78° C. and add AcOH (2.0 ml). Warm to RT, add AcOH:0.1N HCl (15 ml, 1:2) and stir for one hr. Partition between EtOAc and brine. Concentrate the organic layer and purify by silica gel chromatography using EtOAc/Hex 1:3 to elute the title compound (3.6 g 15.7 mmol) as an oil. CI MS: M+1=230.
