Previously, stereoselective hydroxylation of α-ionone by Cytochrome P450 BM3 mutants M01 A82W and M11 L437N was observed. While both mutants hydroxylate α-ionone in a regioselective manner at the C3 position, M01 A82W catalyzes formation of trans-3-OH-α-ionone products whereas M11 L437N

[reaction: see text] The allylic substitution of sterically hindered (2-iodocycloalkyl)phosphates proceeds with complete anti S(N)2' stereoselectivity with mixed diorganozincs of the type RZnCH(2)SiMe(3) in the presence of CuCN.2LiCl. Only the group R of the copper-zinc reagent is transferred in the

To study the influence of the steric bulk of the substituents at C(5) on the olfactory characteristics of alpha-ionone, the (S)-antipodes of compounds 8-10 were synthesized starting from (S)-alpha-cyclogeraniol (14a). The latter was available in useful preparative yield with 95%

Applied and environmental microbiology, 64(10), 3878-3881 (1998-10-06)
A total of 215 Streptomyces strains were screened for their capacity to regio- and stereoselectively hydroxylate beta- and/or alpha-ionone to the respective 3-hydroxy derivatives. With beta-ionone as the substrate, 15 strains showed little conversion to 4-hydroxy- and none showed conversion
