[reaction: see text] The photochemical conversion of 9,10-deoxytridachione to photodeoxytridachione has been photosensitized. The conversion was also quenched by piperylene. Photodeoxytridachione was produced in good yields under conditions in which only the cyclohexadiene group is sensitized. The results show that

The Diels-Alder cycloadditions of trans- and cis-piperylene (1 and 2) to 4-nitroso-N-propylbenzamide (3) were selected as target reactions for the development of catalytic antibodies with regioselective and enantioselective properties (Meekel, A. A. P. Ph.D. Thesis, University of Amsterdam, 1995). The

1,3-Pentadiene, a food contaminant produced by some molds when they metabolize sorbic acid, was tested for mutagenicity, using variations of the Salmonella/mammalian microsome assay. The chemical was incorporated into the test system (with and without S9 mix) by 3 methods:

The ability to resist anti-microbial compounds is of key evolutionary benefit to microorganisms. Aspergillus niger has previously been shown to require the activity of a phenylacrylic acid decarboxylase (encoded by padA1) for the decarboxylation of the weak-acid preservative sorbic acid

Some species of molds are capable of degrading sorbic acid to produce 1,3-pentadiene, a volatile compound with an unpleasant hydrocarbon-like odor. The effectiveness of reduced concentrations of sorbate, in combination with other antimycotics, to control the growth of these molds
