  Asymmetric induction reactions. V. The palladium-catalyzed asymmetric .alpha.-allylation of carbonyl compounds with chiral allyl esters via enamines and imines

  摘要：

  A novel and excellent method for asymmetric alpha-allylation of carbonyl compounds via their chiral enamines or imines bearing allyl eaters has been developed. Readily available chiral allyl eaters having chirality at the alpha-position of the eater carbonyl group, such as (S)-proline and other (S)-alpha-amino acid allyl esters, have been found to serve as good asymmetric allylating reagents in palladium-catalyzed reactions of the chiral enamines and imines derived from them. The use of (S)-proline or (S)-valine allyl esters as the amino parts in the enamines or imines provided the highest optical yields of the corresponding alpha-allyl carbonyl compounds. A mechanism for asymmetric induction is proposed based on the stereochemical results obtained.

  The invention relates to new fluoromethoxyacrylic acid derivatives, a process for their preparation and their use as pesticides, as well as to new intermediates and a plurality of processes for their preparation. It has already been disclosed that certain fluoromethoxyacrylic acid derivatives which are similar in constitution to the compounds described below have fungicidal properties (compare, for example, WO 9517376). The fungicidal action of these compounds, however, is unsatisfactory in many cases.

  本发明涉及新的氟甲氧基丙烯酸衍生物，其制备方法以及它们作为杀虫剂的用途，以及新的中间体和多种制备它们的方法。已经披露了某些与下述化合物相似的氟甲氧基丙烯酸衍生物具有杀真菌作用（例如参见WO 9517376）。然而，这些化合物的杀真菌作用在许多情况下是不令人满意的。
