Reaction Conditions:

with dilithium tetra(tert-butyl)zincate in toluene at 0; for 1 h;Inert atmosphere;

Steps:


General procedure: A typical procedure was as follows. Vinyl acetate (5.0mmol), benzyl alcohol (1.0mmol), and solvent (2.0mL) were added to a glass ampoule which had been degassed and filled with nitrogen. A solution of TBZL (0.1mmol) in THF was added under a nitrogen atmosphere to the ampoule placed in a constant-temperature bath. Then the mixture was kept at 25 or 0°C and stirred. After a prescribed period, the mixture was diluted with CDCl3 and transformed in a NMR tube. Conversion of the reaction was determined by 1H NMR at 400MHz.
