In this manuscript we provide computational support to the catalytic role of water in all kinds of pseudopericyclic reactions operating in the reductive acid cycle, as well as in other metabolic processes. Water catalysis is not limited to those reac

Conscious of the importance that stereochemical issues may have on the design of efficient organocatalyts for both Morita-Baylis-Hillman and aza-Morita-Baylis-Hillman reaction we have analyzed them in this minireview. The so-called standard reactions

The main paradigm of today's chemistry is sustainability. In pursuing sustainability, we need to learn from chemical processes carried out by Nature and realize that Nature does not use either strong acids, or strong bases or fancy reagents to achiev

Organocatalysts displaying a network of cooperative hydrogen bonds (NCHB) have been employed in an enzyme-like manner for a direct, switchable synthesis of enantiopure hexahydropyrimidinones (HHPMs) or dihydropyrimidinones (DHPMs) which starts at a c

The concept of noncovalent organocatalysis by means of networks of cooperative hydrogen bonds (NCHB organocatalysis) has been explored. Arylideneureas were chosen as ideal substrates because of their powerful donor-acceptor properties. We have examin

Enantiomerically enriched trifluoromethyl-substituted alcoholshaving a quaternary center of chirality can be prepared by the catalyticenantioselective addition of carbon nucleophiles to trifluoromethylketones, trifluoropyruvates, or the like. In part

Shelf stable, chiral-at-metal, D3 symmetric, 3:1 complexes of lanthanide (III) triflate salts are easily available by complexation with binolam (3,3′-diethylaminomethyl-2,2′-dihydroxy-1,1′-dinaphthalene) 1 or binolamo (3,3′-diethylaminooxymet

3,3'-Bis(dialkylaminomethyl)-1,1'-binaphth-2-ols (Binolams) have emerged during the last five years as very efficient chiral ligands in many enantioselective processes. Enantiomerically pure Binolams are easily accessible by means of a variety of met

Predictions (DFT/B3LYP calculations) are that cyclopentadienyl lithium edge-fused to [n]circulenes in a circum-like manner should self-assemble as rod-like, nanometer long, supersandwich compounds (see figure). On the contrary, triazolyl lithium anal
