Methyllithium in ether added to a suspension of Cul in the same solvent at —30°, when the soln. became transparent (12 min) a soln. of startg. silylenol phosphate in ether added dropwise, the mixture stirred for 4 h, and quenched with 1 1 satd. NH4Cl/ether - product. Y 90%. The method works best in acyclic systems with highly nucleophilic cuprates, and the regiochemistry complements that of the tosyl-hydrazone route (cf. Synth. Meth. 33, 595s36). F.e. inch cross-coupling with LiCuPh2 s. F.L. Koerwitz et al., J. Org. Chem. 54, 743-7 (1989). [Pg.152]
