Abstract Reactions of alcohols of the adamantane series and adamantan-1-yl nitrates with sulfur nucleophiles in 94% sulfuric acid afforded a number of new sulfur-containing adamantane derivatives such as carbamothioates, isothiocyanates, and carbamodithioates. Di(adamantan-1-yl) disulfide was synthesized by reaction of admantan-1-yl nitrate with sodium sulfide nonahydrate in 94% sulfuric acid.
Alzheimer’s disease is the most common cause of dementia, affecting more than 48 million people worldwide. It has been predicted that by 2050 this figure will be more than 130 million. Alzheimer’s disease is a neurodegenerative disorder characterized by a progressive and irreversible loss of neurons in specific brain regions. The disease gradually affects memory, causes behavior and personality changes

Abstract An efficient approach for the synthesis of aminoalcohols directly from cage hydrocarbons has been developed. Multigram scalability, good yields and one-pot procedure, that utilize readily available reagents along with synthetic convenience showed its usefulness. The proposed one-pot method includes sequential reactions of cage hydrocarbon with nitric acid, further amination of intermediate
摘要 已经开发出一种直接从笼形烃合成氨基醇的有效方法。多克可扩展性、良好的产量和一锅法,利用现成的试剂以及合成的便利性,显示了它的实用性。所提出的一锅法包括笼式烃与硝酸的连续反应,中间体硝基衍生物与尿素的进一步胺化,然后在添加浓溶液时将先前产生的胺氧化成氨基醇。H 2 SO 4。

Abstract N-Adamantylated amides have been synthesized from1-adamantyl nitrate. The reactions were carried out in the sulfuric acid media. The proposed method is usefulness for the preparation of antiviral drug tromantadine. A number of new cage aminoamides have been synthesized by reactions of N-(1-adamantyl)-2-chloroacetamide with nitrogen-containing nucleophiles. with potential biological activity
