  Novel tetrahydropyrimidine–adamantane hybrids as anti-inflammatory agents: synthesis, structure and biological evaluation

  摘要：

  A series of novel (3-((3s,5s,7s)-adamantan-1-yl)-1-alkyl/aralkyl/aryl-1,2,3,4-tetrahydroyrimidin-5-yl)(aryl)methanones (5a-j) has been synthesized by the reaction of 1-aryl-3-(alkyl/aralkyl/aryl)aminoprop-2-en-1-ones 3a-j, 1-adamantanamine 4 and formaldehyde under thermal conditions. The structures of the products (5a-j) have been established with the help of spectral and analytical data. The stereochemistry of the products was established by X-ray crystallographic studies of a representative product (3-((3s,5s,7s)-adamantan-1-yl)-1-methyl-1,2,3,4-tetrahydropyrimidin-5-yl)(4-chlorophenyl) methanone (5g) of the series. The target adamantane-tetrahydropyrimidine hybrids 5a-j were evaluated for their anti-inflammatory activities as a result of which compounds 5e (R=C6H5CH2, Ar=C6H5), 5i (R=CH3, Ar=4-CH3C6H4), 5j (R=C6H5CH2, Ar=4-CH3C6H4) and 5g (R=CH3, Ar=4-ClC6H4 ) were found to exhibit excellent and promising anti-inflammatory activities.

  suggested a novel role for the carbene in the activation of isocyanides, and a proton transfer process was found to be crucial for the generation of two activated species in the catalytic cycle. Various enaminones, some of which are not easily accessible by other methods, were synthesized in excellent yields. This study clearly demonstrates the potential of the nucleophilic activation of isocyanides in

The novel strategy allows for access to a new class of structurally diverse tetrahydro-indolones with high efficiency and a broad substrate scope. In addition, this transformation represents the first example of the selective Rh(III)-catalyzed alkenyl C–H bond functionalization and annulation of enaminones
