In 2019,Molecules included an article by Kong, Rui; Han, Shuai-Bo; Wei, Jing-Ying; Peng, Xiao-Chong; Xie, Zhen-Biao; Gong, Shan-Shan; Sun, Qi. Computed Properties of C7H12O3. The article was titled 《Highly efficient synthesis of substituted 3,4-dihydropyrimidin-2-(1H)-ones (DHPMs) catalyzed by Hf(OTf)4: mechanistic insights into reaction pathways under metal lewis acid catalysis and solvent-free conditionsã€? The information in the text is summarized as follows:

The studies on the catalytic activity of Group IVB transition metal Lewis acids, Hf(OTf)4 was identified as a highly potent catalyst for “”one-pot, three-component”” Biginelli reaction. More importantly, it was found that solvent-free conditions, in contrast to solvent-based conditions, dramatically promoted the Hf(OTf)4-catalyzed formation of 3,4-dihydro-pyrimidin-2-(1H)-ones. To provide a mechanistic explanation, the catalytic effects of Hf(OTf)4 on all three potential reaction pathways in both “”sequential bimol. condensation”” and “”one-pot, three-component”” manners closely examined The exptl. results showed that the synergistic effects of solvent-free conditions and Hf(OTf)4 catalysis not only drastically accelerated Biginelli reaction by enhancing the imine route and activating the enamine route but also avoided the formation of Knoevenagel adduct, which led to an undesired byproduct. In addition, 1H-NMR tracing of the H-D exchange reaction of Me acetoacetate in MeOH-d4 indicated that Hf(IV) cation significantly accelerated ketone-enol tautomerization and activated the β-ketone moiety, thereby contributing to the overall reaction rate.

An environmentally benign decarboxylative cyclization in water has been developed to synthesize 4-quinolones I [R1 = H, 6-Me, 7-Br, 5-Cl, etc.; R2 = Me, Ph, Et, etc.; R3 = C(O)OCH2CH3, C(O)OCH2C6H5, C(O)CH3, etc.] from readily available isatoic anhydrides II and 1,3-dicarbonyl compounds R2C(O)CH2R3. Isatins III (R4 = H, 5-Me, 6-Br, 4-Cl, etc.) are also compatible for the reaction to generate 4-quinolones I in the presence of TBHP in DMSO. This protocol provides excellent yields under mild conditions for a broad scope of 4-quinolones I, and has good functional group tolerance. Only un-harmful carbon dioxide and water are released in this procedure.

《Microscale Parallel Synthesis of Acylated Aminotriazoles Enabling the Development of Factor XIIa and Thrombin Inhibitors》 was written by Platte, Simon; Korff, Marvin; Imberg, Lukas; Balicioglu, Ilker; Erbacher, Catharina; Will, Jonas M.; Daniliuc, Constantin G.; Karst, Uwe; Kalinin, Dmitrii V.. COA of Formula: C7H12O3 And the article was included in ChemMedChem in 2021. The article conveys some information:

Herein we report a microscale parallel synthetic approach allowing for rapid access to libraries of N-acylated aminotriazoles and screening of their inhibitory activity against factor XIIa (FXIIa) and thrombin, which are targets for antithrombotic drugs. This approach, in combination with post-screening structure optimization, yielded a potent 7 nM inhibitor of FXIIa and a 25 nM thrombin inhibitor; both compounds showed no inhibition of the other tested serine proteases. Selected N-acylated aminotriazoles exhibited anticoagulant properties in vitro influencing the intrinsic blood coagulation pathway, but not extrinsic coagulation. Mechanistic studies of FXIIa inhibition suggested that synthesized N-acylated aminotriazoles are covalent inhibitors of FXIIa. These synthesized compounds may serve as a promising starting point for the development of novel antithrombotic drugs.

In 2022,Hati, Santanu; Hu, Qi; Huo, Zhiguang; Lu, Junxuan; Xing, Chengguo published an article in ChemMedChem. The title of the article was 《In vivo Structure-Activity Relationship of Dihydromethysticin in Reducing Nicotine-Derived Nitrosamine Ketone (NNK)-Induced Lung DNA Damage against Lung Carcinogenesis in A/J Mice》.Electric Literature of C7H12O3 The author mentioned the following in the article:

Lung cancer is the leading cause of cancer-related deaths and chemoprevention should be developed. We recently identified dihydromethysticin (DHM) as a promising candidate to prevent NNK-induced lung tumorigenesis. To probe its mechanisms and facilitate its future translation, we investigated the structure-activity relationship of DHM on NNK-induced DNA damage in A/J mice. Twenty DHM analogs were designed and synthesized. Their activity in reducing NNK-induced DNA damage in the target lung tissues was evaluated. The unnatural enantiomer of DHM was identified to be more potent than the natural enantiomer. The methylenedioxy functional moiety did not tolerate modifications while the other functional groups (the lactone ring and the Et linker) accommodated various modifications. Importantly, analogs of high structural similarity to DHM with distinct efficacy in reducing NNK-induced DNA damage have been identified. They will serve as chem. probes to elucidate the mechanisms of DHM in blocking NNK-induced lung carcinogenesis.
