The present technology relates to processes, mixtures and intermediates useful for making picolinamide fungicides. The picolinamide compounds are prepared by processes that include coupling together a 4-methoxy-3-acyloxypicolinic acid with key 2-amino-L-alaninate esters derived from substituted 2-phenylethanols.

Allyl p-tolyl sulphoxide reacts with methanolic sodium methoxide by initial prototropic isomerisation and subsequent addition of methanol to give 2-methoxypropyl p-tolyl sulphoxide. By contrast, reaction with piperidine yields, as the principal products, allyl alcohol and N-p-tolylsulphenylpiperidine. These are formed by nucleophilic displacement at sulphur in the isomer, allyl toluene-p-sulphenate
烯丙基对甲苯基亚砜通过初始质子异构化并随后添加甲醇而与甲醇钠甲醇反应,得到2-甲氧基丙基对甲苯基亚砜。与此相反,用哌啶的产率反应,作为主产物,烯丙醇和ñ - p -tolylsulphenylpiperidine。这些是通过亲核置换,在硫的异构体,烯丙基甲苯形成p -sulphenate其与亚砜平衡。
Silver‐Catalyzed <i>para</i>‐Selective Sulfenyl Group Transfer Reactions of <i>N</i>‐Sulfenylanilides
para-Selective rearrangement reactions of N-sulfenylanilides were efficiently promoted by silver catalysts under mild reaction conditions. This reaction proceeds by an intermolecular transfer of the sulfenyl group.
