This invention relates to the control and/or eradication of Eumycotina type fungi in phanerogamia plants with one or more of the substituted carboxylic amides having the formula: ##STR1## wherein A is an organic radical of from 2 to 14 carbon atoms and is selected from the group consisting of hydroxyalkyl, hydroxyalkoxy, haloalkyl radicals and substituted alkylether radicals having the structure --R.sub.1 --O--R.sub.2 --, where R.sub.1 is alkylene of from 1 to 6 carbon atoms and R.sub.2 is alkyl of from 1 to 6 carbon atoms substituted with a hydroxy, carboxylate or halocarboxylate group; and wherein R is an acyclic alkyl radical, an alkenyl radical having one or more doubly bonded carbon atoms, a mono- or di- fluorinated benzyl radical or a mono- or di- chlorinated benzyl radical, said R radical containing from 4 to 20 carbon atoms. The invention also relates to a method of using a fungicidal amount of said carboxylic acid amide or carboxylic amide mixtures on phanerogamia plants for control or eradication of Eumycotina infection.
conversion of cyclic ketones to lactones by Oxone in neutral buffered water is extended to heterocyclic ketones, namely, cyclic N-Boc azaketones and oxoethers with the aim of obtaining N-protected azalactones and their analogues with oxygen in place of nitrogen. N-Boc-4-piperidinone and all the cyclic oxoethers were successfully oxidized to lactones, while the azacyclic ketones with nitrogen α-positioned

β‐Alkoxy alcohols are selectively oxidized into hemiacetal esters in a one‐pot cascade process, combining a TEMPO‐catalyzed step and a stoichiometric step with a common oxidizing reagent, mCPBA. Under a similar reaction setting, β‐alkoxy 1,2‐diols also form hemiacetal ester products, undergoing a multistep oxidative cascade transformation.
