Paragraph 0225; 0270; 0271, (2019/05/15)
Disclosed are new polycyclic carbogenic molecules and their methods of synthesis. The new polycyclic carbogenic molecules may be utilized in anti-cancer therapies. In particular, the polycyclic carbogenic molecules may be formulated as pharmaceutical comp

The stereoselective oxidative coupling of cyclic ketones via silyl bis-enol ethers followed by ring-closing metathesis is shown to be a general and powerful reaction sequence for the preparation of diverse polycyclic scaffolds from simple precursors. The

Hydrolytic enantioselective protonation of dienyl esters and a β-diketone catalyzed by phase-transfer catalysts are described. The latter reaction is the first example of an enantio-convergent retro-Claisen condensation. Corresponding various optically active α,β-unsaturated ketones having tertiary chiral centers adjacent to carbonyl groups were obtained in good to excellent yields and enantiomeric ratios (83-99%, up to 97.5:2.5 er).
Organocatalytic dynamic kinetic resolution via conjugate addition: Synthesis of chiral trans-2,5-dialkylcyclohexanones
Pandey, Ganesh,Adate, Priyanka A.,Puranik, Vedavati G.
supporting information, p. 8260 - 8267,8 (2020/09/09)
A novel strategy of initiating an organocatalysed dynamic kinetic resolution (dr up to 99:1 and er up to 94:6) for the synthesis of chiral trans-2,5-dialkylcyclohexanones by an asymmetric conjugate addition of dimethyl malonate on to 6-substituted cyclohexenones is reported.
Mn(III)-based oxidative free-radical cyclizations of unsaturated ketones
McCarthy Cole, Bridget,Han, Luning,Snider, Barry B.
, p. 7832 - 7847 (2007/10/03)
Mn(III)-based oxidative free-radical cyclization of unsaturated ketones is a versatile synthetic procedure with broad applicability. For example, oxidation of cyclopentanone 1a with 2 equiv of Mn(OAc)3·2H2O and 1 equiv of Cu(OAc)sub
Intramolecular Cross-ring Enone-Alkene Photoannelation in 6-(ω-Alkenyl)-cyclohex-2-en-1-ones
Lakshmi, A. B.,Rao, Jampani Madhusudana
, p. 476 - 477 (2007/10/02)
The irradiation of some 6-(ω-alkenyl)-cyclohex-2-en-1-ones in micelles gave a carbonyl bridged intramolecular photoadduct but the reaction is restricted to enones tethered to an alkene by not more than a four-carbon chain.
A Novel Synthesis of Bicyclic Isoxazolines via Sequential Michael and Intramolecular 1,3-Dipolar Additions
Uno, Hidemitsu,Watanabe, Noriko,Fujiki, Satomi,Suzuki, Hitomi
, p. 471 - 474 (2007/10/02)
Bicyclic isoxazolines are obtained in good yields by the titanium tetrachloride-mediated reaction of allylic stannanes with 1-nitroalkadienes.Titanium tetrachloride converts stannyl nitronates generated in the Michael addition step to nitrile oxide equiva
