General Description

1-Phenylcyclopentane-1-carboxamide, also known as PCPCA, is a chemical compound with the molecular formula C12H15NO. It is a solid, white crystalline substance that is used in laboratory research as a racemate, meaning it has both R and S enantiomers. PCPCA has been studied for its potential effects on the central nervous system, particularly as a potential analgesic or antinociceptive agent. It has been found to have affinity for the opioid receptors, specifically the δ and κ receptors, and has been investigated for its potential as a non-addictive alternative to traditional opioid pain medications. Further research is needed to fully understand the pharmacological properties and potential therapeutic uses of 1-phenylcyclopentane-1-carboxamide.

Hydration of Cyanohydrins by Highly Active Cationic Pt Catalysts: Mechanism and Scope

Cyanohydrins (α-hydroxy nitriles) are a special type of nitriles that readily decompose into hydrogen cyanide (HCN) and the corresponding carbonyl compounds. Hydration of cyanohydrins that are readily available through cyanation of aldehydes and ketones provides the most straightforward route to valuable α-hydroxyamides. However, due to low stability of cyanohydrins and deactivation of the catalysts by the released HCN, catalytic direct hydration of cyanohydrins still remains largely unsolved. As a general trend, cyanohydrins containing bulkier substituents, such as α,α-diaryl cyanohydrins, degrade more quickly and thus are more difficult to be hydrated. Here, we report development of cationic platinum catalysts that exhibit high reactivity for hydration of various cyanohydrins. Detailed mechanistic investigations for hydration of nitriles by (PμP)Pt(PR2OH)X(OTf) reveal a catalytic cycle involving the formation of a five-membered metallacyclic intermediate and subsequent hydrolysis via attacking on the phosphorus of the secondary phosphine oxide (PR2OH) ligand by H2O. We discovered that Pt catalyst A bearing the electron-rich, appropriately small-bite-angle bisphosphine ligand provides super reactivity for hydration of cyanohydrins. The hydration reactions catalyzed by A proceed at ambient temperatures and occur with a wide variety of cyanohydrins, including the most difficult α,α-diaryl cyanohydrins, with good turnover numbers.

Bridging C?H Activation: Mild and Versatile Cleavage of the 8-Aminoquinoline Directing Group

8-Aminoquinoline has emerged as one of the most powerful bidentate directing groups in history of C?H activation within the last decade. However, cleavage of its robust amide bond has shown to be challenging in several cases, thus jeopardizing the general synthetic utility of the method. To overcome this limitation, we herein report a simple oxidative deprotection protocol. This transformation rapidly converts the robust amide to a labile imide, allowing subsequent cleavage in a simple one-pot fashion to rapidly access carboxylic acids or amides as final products.
