    名称:
    Nouvelle cyclopentannélation regiosélective par une séquence tandem ouverture electrophile/cycloaddition [3+2] entre cétones méthylènecyclopropaniques et l'allyltriméthylsilane
    摘要:
    The TiCL1-mediated reactivity of five complementary substituted methylenecyclopropyl ketones with allyltrimethylsilane has been studied. The regioselectivity of the reaction, which affords functionalized methylene and/or alkylidenecyclopentanes in good yields, depends on the substitution of the cyclopropanic carbon a to the carbonyl function. The reaction occurs via a stereoselective cleavage of the carbocycle followed by a tandem [3+2] cycloaddition of the resultant (Z)-1,3-zwitterion with allyltrimethylsilane that acts as the 1,2-partner in a synclinal approach.

    sufficiently Lewis acidic to catalyze the acetalization of aldehydes and ketones. α,β-Unsaturated substrates can be easily acetalized with ethylene glycol under mild conditions in high yield and avoiding side reactions leading to formation of undesired by-products arising from the nucleophilic addition to the carboncarbon double bond conjugated to the carbonyl group.

    Aldehydes and ketones were efficiently converted to the corresponding acetals by the reaction with ethylene glycol over hydrous zirconium oxide. The reaction could proceed under reflux condition or at room temperature. The compound, which was unstable in acid, was also acetalized by this catalyst.

In both cases, besides expected chloro-adducts, corresponding bromo-adducts are obtained. Formation of these adducts involves halogen exchange by the primary chlorocarbenoid with lithium bromide associated with methyllithium. Conjugated enones give trans α-halocyclopropanic
    共轭烯酮及其二氧戊环的单卤代环丙烷化反应已通过由二氯甲烷和宝石二氯乙烷生成的单卤代碳烯化合物实现。在这两种情况下,除了预期的加合物外,还获得了相应的加合物。这些加合物的形成涉及伯类化合物与与甲基锂缔合的溴化锂之间的卤素交换。共轭烯酮立体定向地产生反式α-卤代环丙醇,而不饱和二氧戊环通常导致反式和反式占主导地位。构型的确定已经通过光谱方法特别是在NMR中的LIS效应来实现。研究和讨论了温度的立体选择性效应和甲基锂试剂的性质。

    The present invention relates to anti-aging agents based on organic compounds containing conjugated azadiene groups, which are capable of providing rubber vulcanizates with long-term protection against thermal aging, fatigue and aging as a result of the effects of oxygen. The anti-aging agents according to the present invention are further characterized in that they are hardly ever extracted from the vulcanizates by water, oils and/or gasolines or hydraulic fluids.
