Preparation of (4R,5R)-2-allyl-2-chloro-4,5-bis-(1-methoxy-1-methyl-[1,3,2]dioxasilolane: To a cooled (0° C.) solution of allyltrichlorosilane (7.0 mL; 48 mmol) in CH2Cl2 (80 mL) was added 1,8-diazabicyclo[5.4.0]undec-7-ene (15 mL; 102 mmol). A solution of (3R,4R)-2,5-dimethoxy-2,5-dimethyl-hexane-3,4-diol (10.0 g; 48 mmol) in CH2Cl2 (80 mL) was then added and the mixture was allowed to warm to ambient temperature and stirred for 12 hours. The solution was concentrated and the residue was treated with diethylether (100 mL). The mixture was stirred for 1 hour. The mixture was then filtered and the filtrate was concentrated. The residue was distilled under reduced pressure to give 6.6 g (44%) of (4R,5R)-2-allyl-2-chloro-4,5-bis-(1-methoxy-1-methyl-ethyl)-[1,3,2]dioxasilolane as a clear, colorless liquid.
