    • The overall yields of chiral dienes 3 a - h are 17-25 % from (-)-bornyl acetate as a 40 % yield of compound 4 was constantly observed. Attempts to optimize the reaction conditions for the preparation of keto acetate 4 by using other oxidants and solvents resulted in no improvement. The fact that (-)-bornyl acetate is inexpensive and the observed high yields and excellent enantioselectivities in the Rh-catalyzed 1,4-addition reaction eliminate concerns over the failure of attempts to improve the yield by optimizing the conditions
