Dynamics of alkylresorcinols during rye caryopsis germination and early seedling growth
Abstract:
Among secondary metabolites, alkylresorcinols are considered particularly important for the antimicrobial defense system in cereal grains. Dry rye caryopses and young seedlings contain detectable quantities of resorcinolic lipids. Overall, 11 distinct alkylresorcinol homologues were identified, which showed variable profiles during rye germination and early seedling development, especially with reference to the production of very long homologues and to side chain saturation. Additionally, changes in the alkylresorcinol composition during rye seedling growth are presented for the first time.

Alkynes to Aldehydes and Ketones: Hydroboration-Oxidation
One of the convenient methods for the preparation of aldehydes and ketones is via hydration of alkynes. Hydroboration-oxidation of alkynes is an indirect hydration reaction in which an alkyne is treated with borane followed by oxidation with alkaline peroxide to form an enol that rapidly converts into an aldehyde or a ketone. Terminal alkynes form aldehydes, whereas internal alkynes give ketones as the final product.
