Efficient Synthesis of 2-Amino-1-Arylethanols Through a Lewis Base-Catalyzed SiCl4-Mediated Asymmetric Passerini-Type Reaction

We herein report, a practical and efficient strategy for the synthesis of enantiomerically enriched 2-amino-1-arylethanols, a structural motif commonly encountered in the family of β-adrenergic blockers or agonists, through a Lewis base-catalyzed SiClsub

Efficient one-pot synthesis of unsymmetrical gold(I) N-heterocyclic carbene complexes and their use as catalysts

Eleven different gold(I) complexes of new NHC ligands were prepared in excellent yield, demonstrating the versatility of the new route to NHC complexes. While the influence of electronically different ligands on the synthesis of the catalysts was small, the catalytic activities of the products differed significantly.

2-Aryl-2-hydroxyethylamine substituted 4-oxo-4,7-dihydrothieno[2,3-b]pyridines as broad-spectrum inhibitors of human herpesvirus polymerases

A novel series of 2-aryl-2-hydroxyethylamine substituted 4-oxo-4,7-dihydrothieno[2,3-b]pyridine-5-carboxamides have been identified as potent antivirals against human herpesviruses. These compounds demonstrate broad-spectrum inhibition of the herpesvirus polymerases HCMV, HSV-1, EBV, and VZV with high specificity compared to human DNA polymerases.

Preparation of phenolic chiral crown ethers and podands and their enantiomer recognition ability toward secondary amines

Phenolic pseudo-24-crown-8 (S,S)-3, pseudo-27-crown-9 (S,S)-4, and podands (R,R)-5 and (R,R)-6 possessing phenyl groups as chiral barriers were prepared and their chiral recognition properties toward secondary neutral amines were examined. Pseudo-24-crown-8 (S,S)-3 and podand (R,R)-5 showed sufficient binding ability and moderate chiral recognition ability toward secondary amines.

Stereoselective synthesis of (1R)- and (1R,2S)-1-aryl-2-alkylamino alcohols from (R)-cyanohydrins

Hydrogenation of (R)-cyanohydrins (R)-1 with LiAlH4 occurs without racemization to give the (R)-2-amino alcohols (R)-3. (1R,2S)-2-Amino alcohols (1R,2S)-4 are obtained with high diastereoselectivity by addition of methyl Grignard to O-silyl protected cyanohydrins (R)-2 and subsequent hydrogenation with NaBH4. The N-alkylated 2-amino alcohols (R)-8 and (1R,2S)-9 can be prepared either by reductive alkylation of the corresponding 2-amino alcohols (R)-3 and (1R,2S)-4, respectively, or by a transimination reaction of the Grignard addition products with primary amines and subsequent hydrogenation with NaBH4. The lower diastereoselectivity of hydrogenation in case of the N-alkylmino compounds in comparison to the N-unsubstituted imines is explained by a weaker chelating effect.

Method of preparing vicinal aminoalcohols

The present invention is concerned with the preparation of N-substituted vicinal aminoalcohol derivatives from the corresponding hydroxyl-protected cyanohydrin derivatives by successive partial reduction, transimination using a primary amine, reduction of the resulting imine and optional removal of the hydroxyl-protecting group. The products are obtained either as a racemate or in an optically pure form, depending upon the stereochemical composition of the starting cyanohydrin derivatives. The present invention is also concerned with certain new enantiomerically pure hydroxyl-protected vicinal aminoalcohols.

Boranes in Synthesis. 6. A New Synthesis of β-Amino Alcohols from Epoxides. Use of Lithium Amides and Aminoborane Catalysts To Synthesize β-Amino Alcohols from Terminal and Internal Epoxides in High Yield

A study of the conversion of terminal and internal epoxides to the corresponding β-amino alcohols using simple primary and secondary lithium amides has been carried out.Thus, styrene oxide and 1,2-epoxydodecane react directly with primary and secondary lithium amides in THF at 25 deg C to give a single regioisomer of the corresponding β-amino alcohols in 80-100percent isolated yields.Since internal epoxides are known to yield predominantly allylic alcohols when reacted with lithium amides, we employed a series of aminoborane Lewis-acid catalists, generated in situ, to suppress formation of the allylic alcohols.Thus, the reaction of cyclohexene oxide with a variety of primary and secondary lithium amides at 34 deg C in diethyl ether in the presence of a catalytic amount of B-bromo-9-BBN afforded the corresponding β-amino alcohols in 70-95percent isolated yield.

Asymmetric syntheses with a new optically active perhydronaphthalene based chiral auxiliary

(1R,4aS,8S,8aS)-8-(5'-Methoxy-2'-methylphenyl)-8-methyldecahydro-1-nap hthalenol 3a is a highly efficient chiral auxiliary in the Diels-Alder addition of its acrylate ester 5 and in the DIBAL-H and Grignard reactions of its phenylglyoxylate ester 7.

Inexpensive Reagents for the Synthesis of Amides from Esters and for Regioselective Opening of Epoxides

Lithium aluminum amides , 6a-6d, easily prepared in Et2O or THF from 1 equiv of LiAlH4 and 5 equiv of amine, proved to be efficient reagents for the synthesis of secondary amides from esters (ca. 100 percent with unhindered amines and 92 percent with t-BuNH2).They also open aryl epoxides with very high regioselectivity to give 97-98 percent of the β-amino-α-arylethanols (corresponding to the SN2 mechanism).
