Relevant academic research and scientific papers

Lewis acid-mediated reaction with silyl ketene acetals and allylstannane of the aluminum acetals generated by DIBALH reduction of α-amino acid esters

The intermediates generated by DIBALH reduction of α-amino acid esters undergo condensation without racemization with silyl ketene acetals and allylstannane in the presence of Lewis acid to afford the corresponding β-hydroxy esters and homoallylic alcohol

A highly stereoselective formal synthesis of hapalosin

A flexible and highly diastereoselective formal synthesis of hapalosin, a cyclodepsipeptide isolated from the blue green alga Hapalosiphon welwitschii and having multidrug-resistance-reversing activity is described. The synthetic route involves the addition of organometallic reagent to N-tert- butanesulfinylimine, Jung nonaldol aldol reaction, and Yamaguchi esterification as key steps.

Selective reductions of oxazolidinones: New protocol for diastereoselective synthesis of vicinal amino alcohols

Selective reductions of oxazolidinones using sodium borohydride and their application to the diastereoselective synthesis of vicinal amino alcohols are described.

ALUMINUM-MEDIATED ONE-POT CONVERSION OF α-AMINO ACID ESTERS TO THREO 2-AMINO ALCOHOLS WITH HIGH DIASTEREOSELECTIVITY

Reduction of N-Cbz α-amino acid esters with DIBAl-H, followed by treatment with Grignard reagent in a one-pot manner gave the corresponding threo 2-amino alcohols with high diastereoselectivity without racemization. KEYWORDS 2-amino alcohol; α-amino acid ester; DIBAL-H reduction; α-amino aldehyde; chelation controll; diastereoselective synthesis; one-pot synthesis

Asymmetric Synthesis of 2- Amino Alcohol Derivatives from (S)-α-Amino Aldehydes via Acetal Templates

Titanium tetrachloride mediated addition of allyltrimethylsilane to chiral acetals derived from (S)-α-amino aldehydes and (+)-(2S,4S)-pentane-2,4-diol gave the anti-2-amino alcohol derivatives with considerably high diastereoselectivity.On the other hand,
