This invention describes the new, nonsteroidal gestagens of general formula I
in which
A, B, Ar, R1, R2 and R3 have the meanings that are indicated in more detail in the description. The new compounds show a very great affinity to the gestagen receptor. They can be used alone or in combination with estrogens in contraceptive preparations. In addition, they can be used for treating endometriosis. Together with estrogens, they can also be used in preparations for treating gynecological disorders, for treating premenstrual symptoms and for substitution therapy. Based on the androgenic action, they can also be used for male birth control, male HRT and hormone therapy and for treating andrological disease agents.
本发明描述了具有一般公式 I 的新非甾体孕激素:其中 A、B、Ar、R1、R2 和 R3 的含义在描述中更详细地指出。这些新化合物对孕激素受体的亲和力非常强。它们可以单独使用,也可以与雌激素结合用于避孕制剂中。此外,它们还可以用于治疗子宫内膜异位症。与雌激素结合时,它们还可用于治疗妇科疾病、治疗经前症状和替代疗法。基于其雄激素作用,它们还可用于男性避孕、男性激素替代疗法和激素治疗,以及治疗男科疾病。

of alkylidenephthalan vinylogous esters. The reaction is selective for the Z alkylidenephthalans in a thermodynamically controlled process. Similar compounds are also produced in the coupling of Fischercarbenecomplexes with 2-alkynylbenzoyl derivatives in an aqueous solvent system. Subsequent acid-catalyzed inter- or intramolecular Diels-Alderreactions lead to hydronaphthalene or hydrophenanthrene

A study of the photochemical reactions of some βγ-unsaturated and γδ-unsaturated 1,2-diketones is reported; it is concluded that the only efficient primary intramolecular processes involve the carbonyl group furthest removed from the alkyl chain, which may undergo cycloaddition via a five-membered transition state to give 5-oxabicyclo-[2,1,1]hexan-2-one derivatives, or γ-hydrogen abstraction leading

Alkenyl N-pivaloylhydroxamates undergo an Ir(III)-catalyzed diamination of the alkene with simple exogenous secondary amines under extraordinarily mild reaction conditions. The regioselectivity of the diamination is controlled by the solvent and the electronics of the cyclopentadienyl (Cpx) ligand on Ir. On the basis of a set of mechanistic experiments, we propose that the relative rates of Ir(V)-nitrenoid
烯基 N-新戊酰基异羟肟酸酯在非常温和的反应条件下,通过 Ir(III) 催化的烯烃与简单的外源仲胺进行二胺化。二化反应的区域选择性受溶剂和 Ir 上环戊二烯基 (Cpx) 配体的电子控制。在一组机械实验的基础上,我们提出 Ir(V)-nitrenoid 形成的相对速率与外源胺对酰胺-Ir-配位烯烃的攻击决定了反应的结果。

A process has been discovered for selective preparation of isomers and enantiomers of 2,2-dimethyl-3-(2,2-dihalovinyl)cyclopropane carboxylic acids. In this process an adduct of an alkyl 3,3-dimethyl-4-pentenoate and a substituted 2-oxazolidone is reacted with a substituted dihalomethane compound. The resulting compound is cyclized, dehydrohalogenated and hydrolyzed to yield the desired product. These cyclopropane carboxylic acids are useful precursors for pyrethroid insecticides.
