Procedure
Similarly to Example 7, 6665.6 mg(5 equivalents) of methyltriphenylphosphonium iodide and 16.5 ml(5 equivalents) of sodium bis(trimethylsilyl)amide-toluene solution(1M) were reacted with 786.0 mg of (1R,3R,3aS,4aR,8aS,9aR)-1-methoxy-3-methyl-4-oxo-dodecahydronaphtho[2,3-c]furan to obtain 683.5 mg of (1R,3R,3aR,4aR,8aS,9aR)-1-methoxy-3-methyl-4-methylene-dodecahydronaphtho[2,3-c]furan(yield 88%).
