Ag(I)-catalyzed Michael additions of β-ketoesters to nitroalkenes in water: Remarkable effect of water as a reaction medium on reaction rates

AgOTf-PPh3 complex-catalyzed Michael additions of β-ketoesters to nitroalkenes in water were performed. The system promotes the reaction efficiently only in water, and interestingly the reaction does not proceed well in organic solvents. In add

Molecular Engineering of β-Substituted Oxoporphyrinogens for Hydrogen-Bond Donor Catalysis

A new class of bifunctional hydrogen-bond donor organocatalyst using oxoporphyrinogens having increased intramolecular hydrogen-bond donor distances is reported. Oxoporphyrinogens are highly non-planar rigid macrocycles containing a multiple hydrogen bond-forming binding site. In this work, we describe the first example of non-planar OxPs as hydrogen-bond donor catalysts prepared using a molecular engineering approach of the binding site for dual activation of substrates. The introduction of β-substituents is key to the catalytic activity and the catalysts are able to catalyze 1,4-conjugate additions and sulfa-Michael additions, as well as, Henry and aza-Henry reactions at low catalyst loadings (≤ 1 mol-%) under mild conditions. Preliminary mechanistic studies have been carried out and a possible reaction mechanism has been proposed based on the bi-functional activation of both substrates through hydrogen-bonding interactions.

1,3-Diamine-Derived Bifunctional Organocatalyst Prepared from Camphor

Chiral 1,2-diamines are privileged structural motifs in organocatalysis, whereas efficient 1,3-diamine-derived organocatalysts are very rare. Herein we report a highly efficient camphor-1,3-diamine-derived squaramide organocatalyst. Its catalytic activity

A 4-amino-3-phenyl-butyric acid hydrochloride method for the synthesis of

A provided synthetic method for 4-amino-3-phenylbutyric acid hydrochloride comprises the steps: preparing ethyl benzoylacetate, preparing nitroethenylbenzene, preparing an addition product, and processing to obtain the product. The synthetic method is an integral technology for synthesizing 4-amino-3-phenylbutyric acid hydrochloride. The method is simple in technology, high in yield and relatively low in cost, and mainly solves the problems that an initial raw material used in the prior art is high in price, operation steps are tedious and a production process is large in pollution.

Novel Chiral Bifunctional L-Thiazoline-Thiourea Derivatives: Design and Application in Enantioselective Michael Reactions

Several novel chiral bifunctional L-thiazoline-thiourea derivatives were easily synthesized from commercially available L-cysteine in high yield. These catalysts were subsequently applied to the enantioselective Michael addition of acetylacetone to β-nitr

Mechanosynthesis of γ-nitro dicarbonyl compounds via CaCl 2-catalyzed Michael addition
