generally furnished analogues like 4'-fluoroacetoacetanilide (7) and ethyl 4'-fluoromalonanilate (1), which induced 89.12 and 84.66% male sterility, respectively, in PBW 343. Among halogenated acetanilides, the increasing number of chlorine atoms in the side chain led to an increase in the activity of 4'-fluoro (23) and 4'-bromo (24) derivatives of trichoroacetanilides, which induced >87% male sterility. Quantitative
通过部署化学杂交剂(CHA)诱导雄性不育在自花授粉作物(如小麦)的杂种育种中很重要,其中雄性和雌性器官都在同一朵花中。在较早的水稻研究工作的牵头下,合成了总共25种由丙二酸,乙酰乙酰苯胺和乙酰苯胺(包括卤代乙酰苯胺)组成的N-酰基苯胺,并将其筛选为三种小麦基因型的CHAs,即PBW 343,HD 2046。 ,以及2001-2002年冬季的1500 ppm HD 2733。通过将取代的苯胺与适当的二酯,酰氯或单酯缩合来合成在酰基和芳族结构域上具有变化的N-丙氨酸。经鉴定,在芳基环对位具有高电负性基团(例如F / Br)的测试化合物是最有效的CHAs,可引起更高的雄性不育性。N取代在侧链上的变化通常提供类似物,如4'-氟乙酰乙酰苯胺(7)和4'-氟丙二酸乙基苯酯(1),它们分别在PBW 343中引起89.12和84.66%的雄性不育。侧链中氯原子数目的增加导致三氯乙酰苯胺的4'-氟(23)和

The 1:1 reactive intermediates produced in the reaction between alkyl isocyanides and dialkyl acetylenedicarboxylates were trapped with N-aryl-2,2,2-trichloroacetamides. When the aryl group was 1-naphthyl, two products were obtained in nearly 2:1 ratio.
