New analogues of (Z)-dodec-8-en-1-yl acetate (Z8-12:OAc, 1), the main sex pheromone component of the Oriental fruit moth, Cydia molesta, were designed by formally transferring the terminal propyl group from the C-9 to the C-7 position to form vinyl-b

The stereoselectivity of the reduction of rac-3-methyl-1-(phenylsulfonyl)hexan-2-one (1) to 3-methyl-1-(phenylsulfonyl)hexan-2-ol (2) diastereomers by more than 20 yeasts was studied. Reduction of carbonyl group in 1 proceeds with a high Re-face enan
