Cinchona Alkaloid Catalyzed Sulfa-Michael Addition Reactions Leading to Enantiopure beta-Functionalized Cysteines

Sulfa-Michael additions to alpha,beta-unsaturated N-acylated oxazolidin-2-ones and related alpha,beta-unsaturated alpha-amino acid derivatives have been enantioselectively catalyzed by Cinchona alkaloids functionalized with a hydrogen bond donating group at the C6? position. The series of Cinchona alkaloids includes known C6? (thio)urea and sulfonamide derivatives and several novel species with a benzimidazole, squaramide or a benzamide group at the C6? position. The sulfonamides were especially suited as bifunctional organocatalysts as they gave the products in very good diastereoselectivity and high enantioselectivity. In particular, the C6? sulfonamides catalyzed the reaction with the alpha,beta-unsaturated alpha-amino acid derivatives to afford the products in a diastereomeric ratio as good as 93:7, with the major isomer being formed in an ee of up to 99%. The products of the organocatalytic sulfa-Michael addition to alpha,beta-unsaturated alpha-amino acid derivatives were subsequently converted in high yields to enantiopure beta-functionalized cysteines suitable for native chemical ligation.

1,4-Dioxane, a suitable scaffold for the development of novel M3 muscarinic receptor antagonists

In this study the modulation of the pharmacological profile from agonist to antagonist was successfully obtained by replacing the methyl group in position 6 of the 1,4-dioxane scaffold of the potent M2/M3 muscarinic agonist 1 with bulkier groups. In particular, the 6,6-diphenyl substitution provided the potent M3 preferring antagonist (±)-17, which in in vivo study proved to be effective in reducing the volume-induced contractions of rat urinary bladder and was devoid of cardiovascular effects.

Synthesis of Ethylene Glycol from Syngas via Oxidative Double Carbonylation of Ethanol to Diethyl Oxalate and Its Subsequent Hydrogenation

This work reports a novel sustainable two-step method for the synthesis of ethylene glycol (EG) using syngas. In the first step, diethyl oxalate was selectively synthesized via oxidative double carbonylation of ethanol and carbon monoxide (CO) using a ligand-free, recyclable Pd/C catalyst. In the second step, the diethyl oxalate produced underwent subsequent hydrogenation using [2-(di-tert-butylphosphinomethyl)-6-(diethylaminomethyl)pyridine]ruthenium(II) chlorocarbonyl hydride to get EG and ethanol. Thus, the generated ethanol can be recycled back to the first step for double carbonylation. This method gives a sustainable route to manufacture EG using carbon monoxide and hydrogen.

An efficient enantioselective synthesis of cermizine D has been developed that exploits the use of a common intermediate to access over 85% of the carbon backbone. Key steps include an organocatalyzed heteroatom Michael addition, a diastereoselective alkylation with alpha-iodomethyl phenyl sulfide, a conjugate addition to a vinyl sulfone species, and a sulfone coupling/desulfurization sequence to join the two major subunits.

Multifunctional biocompatible and biodegradable folic acid conjugated poly(epsilon-caprolactone)-polypeptide copolymer vesicles with excellent antibacterial activities

Cancer patients after chemotherapy may also suffer bacterial attack due to badly decreased immunity. Although with high bacterial efficacy, conventional antibiotics are prone to inducement of drug resistance and may be not suitable for some cancer patients. In contrast, antibacterial peptides are highly effective in inhibiting bacteria without inducing resistance in pathogens. Presented in this article is a novel kind of highly effective antibacterial peptide-based biocompatible and biodegradable block copolymer vesicle. The copolymer is poly(epsilon-caprolactone)-block-poly[phenylalanine-stat-lysine-stat-(lysine-folic acid)] [PCL19-b-poly[Phe12-stat-Lys9-stat-(Lys-FA)6]], which can self-assemble into vesicles in aqueous solution. The biocompatible and biodegradable PCL forms the vesicle membrane, whereas the poly[Phe12-stat-Lys9-stat-(Lys-FA)6] block constitutes the vesicle coronas. Compared to the individual polymer chains, the vesicles showed enhanced antibacterial activities against both Gram-positive and Gram-negative bacteria (16 mug mL-1) due to the locally concentrated antibacterial poly[Phe12-stat-Lys9-stat-(Lys-FA)6] coronas, which may avoid the inducement of antibiotic-resistant bacteria and side effects of multidrug interactions. Furthermore, folic acid is introduced into the vesicle coronas for potential further applications such as cancer-targeted drug delivery. Moreover, the amino groups can be further functionalized when necessary. This low cytotoxic, biocompatible, biodegradable, and antibacterial vesicle (without antibiotic resistance) may benefit patients after tumor surgery because it is highly anti-inflammatory, and it is possible to deliver the anticancer drug to tumor cells simultaneously.
