ABSTRACT The cumulative effects of constructed dams on the mainstream Mekong River and its tributaries are transforming fundamental characteristics river regime with pervasive repercussions not only for natural systems but also social economies. In this context, study addresses issues identified above by coupling reservoir model from CaMa-Flood-Dam Watershed Environmental Hydrology Model . proposed models were well calibrated validated before embarking assessment dam effects. results showed...
β-Amino acids might be regarded as the building blocks that nature overlooked. Although seldom used in nature, scientists have recognized importance of β-amino design many molec...
Abstract Various chiral N ‐phosphonyl β‐amino Weinreb amides were synthesized by treating imines with the lithium enolate of ‐methoxy‐ ‐methylacetamide. The , ‐protection groups on and types deprotonation bases for generation found to be crucial successful synthesis. Eleven obtained in excellent chemical yields (92 98 %) good diastereoselectivities (up dr = 99:1). absolute structures unambiguously determined converting products into authentic samples comparing their optical rotation...
A trisulfur-radical-anion (S3̇–)-triggered C(sp2)–H amination of α,β-unsaturated carbonyl derivatives with simple amines has been demonstrated. This protocol provides convenient access to a variety synthetically valuable N-unprotected and secondary β-enaminones absolute Z selectivity tertiary E selectivity. Mechanistic probe electronic structure theory calculations suggest that S3̇– initiates the nucleophilic attacks via thiirane intermediate.
Chiral phosphonyl imines attached by 1-naphthyl protection group were found to react with lithium ester enolates smoothly and give chiral beta-amino esters in good yields (70-88%) up excellent diastereoselectivity (>99:1 dr). Triisopropoxytitanium (IV) chloride was enhance diastereoseletivity when used as the Lewis acid promoter. The auxiliary can be readily removed treating HBr free amino esters. absolute structure has been unambiguously determined converting one of products into an...
Pyrido-fused quinazolinones were synthesized <italic>via</italic> copper-catalyzed cascade C(sp<sup>2</sup>)–H amination and annulation of 2-aminoarylmethanols with isoquinolines or pyridines.
A simple metal-free method for the synthesis of quinazolinones from commercially available 2-nitrobenzyl alcohols and tetrahydroisoquinolines is developed. The reaction conditions were tolerant an array functionalities such as halogen, tertiary amine, protected alcohol, ester groups. Under nearly identical conditions, quinazolinethiones obtained in presence elemental sulfur suitable mediators.
The synthesis of (2S)-2-benzyloxymethyl-3-(2-fluoro-4-methoxyphenyl)- propionic acid, (2S)-2-benzyloxymethyl-3-(2-fluoro-4-methylphenyl)propionic acid and (2S)-2-benzyl-oxymethyl-3-(2,4-dimethylphenyl)propionic has been achieved by TiCl4 mediated alkylation the corresponding (4R)-4-benzyl-3-[3-(2-fluoro-4-methoxyphenyl-, 2-fluoro-4-methylphenyl-, 2,4- dimethylphenyl-)propionyl]-2-oxazolidinones, followed hydrolysis chiral auxiliary. stereochemistry reaction was confirmed an X-ray crystal...
Abstract A method for assembling chalcones, glycine ethyl ester hydrochloride, and elemental sulfur toward a synthesis of 4,5-disubstituted thiazoles is reported. The transformation presumably proceeds via sequence β-C–H amination, annulation, dealkoxycarbonylation. This tactic represents rare example obtaining such disubstituted directly from chalcone C–H bonds.

The metal organic frameworks material (CuOBA) was synthesized by solvothermal method. physicochemical characteristics of this solid catalyst were determined a number different analytical techniques including X-ray powder diffraction (XRD), scanning electron microscopy (SEM), transmission (TEM), thermogravimetric analysis (TGA), and Fourier transform infrared (FT-IR). CuOBA used as heterogeneous for the coupling reaction C=O connection between 5’- bromo - 2’-hydroxiacetophenone benzyl ether...
