Lipase B from Candida antarctica catalyzes the oxidative ring expansion of furfuryl alcohols using aqueous hydrogen peroxide to yield functionalized pyranones under mild conditions. The method further allows for the preparation of corresponding piperidinone derivatives by enzymatic rearrangement of N-protected furfurylamines.
来自南极念珠菌的脂肪酶 B 使用过氧化氢水溶液催化糠醇的氧化扩环,在温和条件下产生官能化的吡喃酮。该方法还允许通过N-保护的糠胺的酶促重排来制备相应的哌啶酮衍生物。

The present invention is directed to compounds of general formula I as well their pharmaceutically and veterinarily acceptable acid addition salts or hydrates thereof. The present invention is further directed to pharmaceutical and veterinary compositions containing the compounds of general formula I. The present compounds of general formula I are antagonist of platelet activating factor (PAF). Accordingly, the present invention is also directed to methods for preventing, treating or ameliorating in human or mammalian animals, various diseases or physiological conditions mediated by PAF.

(EN) Compounds of general formula (I); and their pharmaceutically and veterinarily acceptable acid addition salts and hydrates are antagonists of platelet activating factor (PAF) and as such are useful in the treatment or amelioration of various diseases or disorders mediated by PAF.(FR) Des composés de la formule générale (I) ainsi que leurs hydrates et leurs sels d'addition d'acide acceptables d'un point de vue pharmaceutique et vétérinaire, sont des antagonistes du facteur d'activation plaquettaire (PAF) et, en tant que tels, peuvent être utilisés dans le traitement ou la guérison de différentes maladies ou affections induites par PAF.
The present invention relates to the use of pyrimidine compounds of formula (I),
or their agriculturally acceptable salts or derivatives as herbicides, wherein the variables are defined according to the description, specific pyrimidine compounds of formula (I), compositions comprising them and their use as herbicides, i.e. for controlling harmful plants, and also a method for controlling unwanted vegetation which comprises allowing a herbicidal effective amount of at least one pyrimidine compounds of the formula (I) to act on plants, their seed and/or their habitat.
