In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called N-Substituted S-Alkyl Carbamothioates in the Synthesis of Nitrogen-containing Functional Derivatives of the Adamantane Series, published in 2021-08-31, which mentions a compound: 56621-48-8, mainly applied to urea adamantyl preparation; urethane adamantyl preparation, Recommanded Product: 4-(Piperazin-1-yl)phenol.
A series of new asym. ureas, urethanes, and other derivatives of the framework structure I [R = OCH2C2OH, (2-methylquinolin-4-yl)aminyl, 4-methylpiperazin-1-yl.HCl, etc.] have been synthesized by the reactions of adamantan-1-yl isocyanate generated in situ by the thermolysis of S-Et (adamantan-1-yl)carbamothioate with nitrogen-containing nucleophiles and alcs.
Although many compounds look similar to this compound(56621-48-8)Recommanded Product: 4-(Piperazin-1-yl)phenol, numerous studies have shown that this compound(SMILES:OC1=CC=C(N2CCNCC2)C=C1), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
