High impact information on R-Pentine

• The tris(p-bromophenyl)aminium hexachloroantimonate (1(*)(+)SbCl(6)(-))-initiated reactions of phenylvinylsulfide (2) and cyclopentadiene (3) and of trans-anethole (5) and isoprene (6) and the dimerization of 1,3-cyclohexadiene (8) to give the respective Diels-Alder products were studied [1].
• Self-activated supramolecular reactions: effects of host-guest recognition on the kinetics of the Diels-Alder reaction of open-chain oligoether quinones with cyclopentadiene [2].
• In contrast, formation of discrete complexes between nucleotides and the biologically inactive metallocenes Cp2MCl2 (M = Hf, Zr, 0.25-1.00) is not observed, and instead hydrolysis of the Cp rings to give free cyclopentadiene is the major reaction pathway [3].
• N-Allenylsulfenimide 2b smoothly undergoes catalytic hydrogenation and a Diels-Alder reaction with cyclopentadiene [4].
• [structure: see text] Platinum(II) terpyridyl acetylide complex (1) was incorporated into Nafion membranes as a photosensitizer, and the Nafion was immersed in an aqueous or organic solution of 7-dehydrocholesterol, alpha-pinene, or cyclopentadiene [5].

Biological context of R-Pentine

• An unexpected bispericyclic transition structure leading to 4+2 and 2+4 cycloadducts in the endo dimerization of cyclopentadiene [6].
• A QSAR using Comparative Molecular Field Analysis (CoMFA) is developed for a set of 23 catalysts containing bisoxazoline or phosphinooxazoline ligands that are known to induce asymmetry during the Diels-Alder reaction of N-2-alkenoyl-1,3-oxazolidine-2-one with cyclopentadiene [7].

Associations of R-Pentine with other chemical compounds

• We have studied the kinetics of the Diels-Alder reactions of cyclopentadiene, sorbyl alcohol, and sorbyltrimethylammonium bromide with a series of N-substituted maleimides in micellar media [8].
• Theoretical study on chlorine and hydrogen shift in cycloheptatriene and cyclopentadiene derivatives [9].
• Theoretical study on the Diels-Alder reaction between 2-methylacrolein and cyclopentadiene catalyzed by a cationic oxazaborolidine Lewis acid [10].
• A Diels-Alder reaction of 3,4-dehydroproline derivative 9 and cyclopentadiene afforded a single stereoisomer 11 [11].
• In addition to hexachlorbenzene (HCB), three groups of organochlorine compounds namely, DDT and its metabolites, hexachlorcyclohexane (HCH-isomers) and the cyclopentadiene group (aldrin, dieldrin, endrin, heptachlor, and heptachlor epoxide) were analyzed [12].

Gene context of R-Pentine

• The three reactions investigated here include the acyl chain cross-linking between thiol and bromine groups, thiol and acryloyl groups, and cyclopentadiene and acryloyl groups [13].
• Thus, we have prepared a series of p-hydroxyphenyl-substituted CpRe(CO)(3) complexes and evaluated them (and, in some cases, their cyclopentadiene precursors) for binding to ER [14].
• New carbocyclic c-nucleoside precursors have been synthesized in stereocontrolled manner by nonoxidative C-C bond fission (i.e., Grob fragmentation or retrograde aldol reaction) starting from Diels-Alder adducts of cyclopentadiene with 3-acetoxyacrylates or dimethyl 2-acetoxymethylenemalonate [15].
