Chiral benzimidazoles as hydrogen bonding organocatalysts [PDF]
, 2015 Several bifunctional organocatalysts bearing the benzimidazole unit have been designed in order to act as bifunctional systems by hydrogen bonding. Chiral 2-aminobenzimidazoles are conformational rigid guanidines able to catalyze enantioselectively ...

Addition-substitution reactions of 2-thio-3-chloroacrylamides with carbon, nitrogen, oxygen, sulfur and selenium nucleophiles [PDF]
, 2011 Synthetically versatile conjugate addition of a range of carbon, nitrogen, oxygen, sulfur and selenium nucleophiles to the highly functionalised 2-thio-3-chloroacrylamides is described.

The FEBS Journal, EarlyView.Quinolones are valuable scaffolds for drug discovery but are rare in nature. Here, we show that two fungal enzymes, AthePKS and FerePKS, can generate 2‐quinolones and two additional heteroaromatic scaffolds. Using AthePKS, we designed an artificial enzymatic cascade towards an antimicrobial quinolone from a simple precursor and implemented it in E ...

The degradation of L-lysine in guinea pig liver homogenate: formation of alpha-aminoadipic acid [PDF]
, 1948 A summary of the little that is known of the metabolism of lysine in animals is as follows: it is indispensable in the diet, its α-amino group does not participate in reversible transamination reaction in vivo (2), neither the L nor D form is attacked by

Journal of Physical Organic Chemistry, Volume 39, Issue 2, February 2026.The electrophilicities (Mayr E) of the α, β‐unsaturated ketones A and B were determined by kinetic studies of their reactions with carbanions (reference nucleophiles) in DMSO at 20°C. The different reactivities of A and B were rationalized by DFT calculations.

The synthesis and biodistribution of 3‐(4′‐[ 125 I]‐iodophenyl)‐4‐aminobutyric acid, a radioiodinated analogue of baclofen [PDF]
, 1990 Baclofen has been found to bind to receptors in the central nervous system that are specific for γ‐aminobutyric acid (GABA), a well known inhibitory neurotransmitter. This paper describes the synthesis of a radioiodinated analog of baclofen as part of an

European Journal of Organic Chemistry, Volume 29, Issue 2, January 16, 2026.We synthesized a series of light to heavy fluorous Hoveyda–Grubbs precatalyst analogs modified in the alkoxybenzylidene part in positions 2 and 5 by long (fluorinated) ponytails and tested their activity in ring‐closing metathesis. The substitution mostly resulted in accelerated reaction but the precatalyst stability often decreased.
