Compounds of the type 65 have been prepared by opening of the epoxide ring of l-(2,3-anhydro-5-0-trityl-P-D-lyxofuranosyl)uracil with a variety of carbon nucleophiles such as ethynyl lithium, vinylmagnesium bromide/cuprous iodide and l,3-dithian-2-yl lithium. These reactions afforded regioselectively 3 -C-substituted-3 -deoxy-P-D-arabinofuranosyl nucleosides 69-71 in 10-68% yield [84, 87] (Fig. 12). These intermediates have been transformed into a variety of other 3 -C-substituted-3 -deoxy-arabinofuranosyl uridines 72-77 [84]. 9-(3-Deoxy-3-C-methyl-P-D-xylofuranosyl)adenine has been prepared by glycosidation reaction of a 3-deoxy-3-C-methyl-P-D-xy/ofuranosyl chloride with adenine [90].

A number of examples for the copper-catalyzed carbometallation151,300,300a or stannylmetallation61,61a of G-G double or triple bonds have been described in recent years. For example, reaction of ethynyl carbamate 346 with n-butylmagnesium bromide in the presence of 10 mol.% of copper(i)-iodide induced a smooth regio- and stereoselective carbomagnesiation to afford the vinylmagnesium intermediate 347 which can be trapped with benzaldehyde to the allyl alcohol 348 (Scheme 97).151... 

Vinyl halides. Vinyl halides, even the iodide, are not convertible to Grignard reagents by the usual procedure, but Normant found that vinyl chloride and vinyl bromide readily form vinylmagnesium halides in solution in tetrahydrofurane (THF) or in a diether of di- or triethylene glycol. See review. ...
