Ruthenium-catalyzed intermolecular [2+2+2] alkyne cyclotrimerization in aqueous media under microwave irradiation

Green Chemistry Letters and Reviews (2011)

Victorio Cadierno Javier Francos Sergio E. García‐Garrido José Gimeno

The ability of the bis(allyl)-ruthenium(IV) complex [{RuCl(µ-Cl)(η3: η3-C10H16)}2] (C10H16=2,7-dimethylocta-2,6-diene-1,8-diyl) to promote intermolecular [2+2+2] alkyne cyclotrimerization reactions in aqueous media under microwave (MW) irradiation has been evaluated. Advantages and disadvantages of using MW vs. conventional thermal heating are discussed.

Anion receptors based on organic frameworks: highlights from 2005 and 2006

Chemical Society Reviews (2007)

Philip A. Gale Sergio E. García‐Garrido J. Garric

This critical review covers advances in anion complexation chemistry related to receptors based on organic frameworks in the years 2005-2006. The review covers anion receptors that employ amides and thioamides, pyrroles and indoles, ureas and thioureas, ammonium, guanidinium, imidazolium, and receptors containing hydroxyl groups. There is a discussion of anion templated assembly, followed by a short section outlining modelling studies of these systems. (226 references.)

Efficient Intermolecular [2 + 2 + 2] Alkyne Cyclotrimerization in Aqueous Medium Using a Ruthenium(IV) Precatalyst

Journal of the American Chemical Society (2006)

Victorio Cadierno Sergio E. García‐Garrido José Gimeno

The dimeric bis(allyl)-ruthenium(IV) complex [{Ru(eta3:eta3-C10H16)(mu-Cl)Cl}2] (C10H16 = 2,7-dimethylocta-2,6-diene-1,8-diyl) was found to catalyze efficiently the [2 + 2 + 2] cyclization of terminal and internal alkynes in aqueous medium.

Asymmetric Hydrogenation of 1-Alkyl and 1-Aryl Vinyl Benzoates: A Broad Scope Procedure for the Highly Enantioselective Synthesis of 1-Substituted Ethyl Benzoates

ACS Catalysis (2014)

Patryk Kleman Pedro J. González‐Liste Sergio E. García‐Garrido Victorio Cadierno Antonio Pizzano

The enantioselective hydrogenation of enol esters of formula CH2═C(OBz)R with rhodium catalysts based on phosphine–phosphite ligands (P–OP) has been studied. The reaction has a broad scope, and it is suitable for the preparation of products possessing a wide variety of R substituents. For the cases where R is a primary alkyl, high catalyst activity (S/C = 500) and enantioselectivities (95–99% ee) were obtained with a catalyst characterized by an ethane backbone and a PPh2 fragment. In contrast, for R = t-Βu, a catalyst possessing a benzene backbone provided the best results (97% ee). Derivatives with a cycloalkyl R substituent were particularly difficult substrates for this reaction. A broader catalyst screening was required for these substrates, which identified a catalyst possessing a P(m-xylyl)2 fragment as the most appropriate one, affording enantioselectivities between 90 and 95% ee. Outstanding enantioselectivities (99% ee) and high catalyst activity (S/C = 500–1000) were also obtained in the case of substrates bearing a Ph or a fluoroaryl R substituent. In addition, the system is also appropriate for the preparation of other synthetically useful esters as those for R = benzyl, 2-phenylethyl or N-phthalimido alkyl chains. Likewise, the hydrogenation of divinyl dibenzoates proceeded with very high diastero- and enantioselectivity, generating rather low amounts of the meso isomer (3–6%). On the other hand, substrates with Br and MeO substituents at the phenyl benzoate ring, suitable for further functionalization, have also been examined. The results obtained indicate no detrimental effect of these substituents in the hydrogenation. Alternatively, the methodology has been applied to the highly enantioselective synthesis of deuterium isotopomers of 1-octyl benzoate bearing CDH2, CD2H, or CD3 fragments. Finally, as a practical advantage of the present system, it has been observed that the high performance of the catalysts is retained in highly concentrated solutions or even in the neat substrate, minimizing both the amount of solvent added and the volume of the reaction.

Isomerization of Propargylic Alcohols into α,β‐Unsaturated Carbonyl Compounds Catalyzed by the Sixteen‐Electron Allyl‐Ruthenium(II) Complex [Ru(η³‐2‐C₃H₄Me)(CO)(dppf)][SbF₆]

Advanced Synthesis & Catalysis (2006)

Victorio Cadierno Sergio E. García‐Garrido José Gimeno

Abstract The 16‐e − (η 3 ‐allyl)‐ruthenium(II) complex [Ru(η 3 ‐2‐C 3 H 4 Me)(CO)(dppf)][SbF 6 ] is an efficient catalyst for the regioselective isomerization of terminal propargylic alcohols HCCCR 1 R 2 (OH) into α,β‐unsaturated aldehydes R 1 R 2 CCHCHO or ketones R 3 R 4 CC(R 1 )COMe (if R 2 =CHR 3 R 4 ) under mild conditions. This complex has been also used as catalyst for the preparation of conjugated 1,3‐enynes via dehydration of propargylic alcohols.
