METABOLISM OF ABSCISIC ACID: BACTERIAL CONVERSION TO DEHYDROVOMIFOLIOL AND VOMIFOLIOL DEHYDROGENASE ACTIVITY

A species of Corynebacterium, capable of metabolizing abscisic acid (ABA), was isolated from soil.The organism converted ABA to dehydrovomifoliol as the major metabolite.A cell-free extract exhibited vomifoliol dehydrog

Novel synthesis of degradation products of carotenoids, megastigmatrienone analogues and blumenol-A

Synthesis of 4-alkylidene-3,5,5-trimethylcyclohex-2-enones 7 has been achieved utilising 1,4-conjugate dehydrobromination of allylic bromides 5 as a key step. This chemical transformation is applied to the synthesis of degradation products of carotenoids: megastigmatrienones 7e/1-4,4-methylene-3,5,5-trimethylcyclohex-2-enone 7a, 4-(3-hydroxybutylidene)-3,5,5-trimethylcyclohex-2-enone 9,1,3,7,7-tetramethyl-2-oxabicyclo[4.4.0]dec-5-en-9-one 10a-b and 3,4,7,8-tetrahydro-4,4,7-trimethylnaphthalen-2(6H)-one 15. A novel photoisomerisation of 4-[(Z)-3-acetoxybut-2-enyl]-4-hydroxy-3,5,5-trimethylcyclohex-2-enone 19 to 4-[(E)-3-acetoxybut-2-enyl]-4-hydroxy-3,5,5-trimethylcyclohex-2-enone 20 enables us to synthesise blumenol-A 21.

Norisoprenoids in Vitis vinifera White Wine Grapes and the Identification of a Precursor of Damascenone in These Fruits

Twenty-four norisoprenoids, which are either free volatile components of juices of Vitis vinifera cvv.Chardonnay, Semillon and Sauvignon Blanc, or are liberated by glycosidase enzyme, or acid hydrolysis of extracts of these juices, have been identified.Eleven of these norisoprenoids are reported as grape products for the first time.The hypothetical 7-oxomegastigmane precursors, grasshopper ketone (5) and megastigm-5-en-7-yne-3,9-diol (10), as well as the related allene, 9-hydroxymegastigma-4,6,7-trien-3-one (6), have been observed for the first time, cooccurring with damascenone (1), 3-hydroxy-β-damascone (2), 3-oxo-β-damascone (3) and 3-oxo-α-damascone (4).Hydrolytic studies have shown that megastigm-5-en-7-yne-3,9-diol (10) is a precursor of damascenone (1) and 3-hydroxy-β-damascone (2) during wine conservation.
