Stereoselective synthesis of dehydroamino acids using malonic acid half oxyester and aromatic aldehydes
Singjunla, Yuttapong,Colombano, Silvia,Baudoux, Jér?me,Rouden, Jacques
, p. 2369 - 2375 (2016/04/26)
An efficient and direct approach was developed for the synthesis of α,β-dehydroamino acid derivatives with a broad range of substrates. Amido-substituted Malonic Acid Half Oxyesters (MAHOs) have proven to be excellent partners of various aromatic aldehyde
A new and convenient method for the synthesis of dehydroamino acids starting from ethyl N-Boc- and N-Z-α-tosylglycinates and various nitro compounds
Nagano, Tanemasa,Kinoshita, Hideki
, p. 1605 - 1613 (2007/10/03)
Ethyl N-Boc- and N-Z-α-tosylglycinates, which were readily available from t-butyl or benzyl carbamate, ethyl glyoxylate, and sodium p- toluenesulfinate in formic acid, were reacted with a variety of nitro compounds in the presence of a base to afford the corresponding α,β- didehydroamino acid derivatives in good yields. Eventually, it was found that the (Z)-isomer was predominantly formed in the present method.
Palladium-Catalyzed Synthesis of Didehydroamino Acid Derivatives
Carlstroem, Anne-Sofie,Frejd, Torbjoern
, p. 414 - 418 (2007/10/02)
The palladium-catalyzed coupling of 2-amidoacrylates with aryl iodides under phase-transfer conditions yields aromatic (Z)-didehydroamino acid derivatives, which give various protected aromatic amino acids via catalytic hydrogenation using Pd/C or the Wil
Horner Synthesis of Didehydroamino Acid Derivatives in a Liquid-Liquid Two-Phase System
Ciattini, Pier Giuseppe,Morera, Enrico,Ortar, Giorgio
, p. 140 - 142 (2007/10/02)
Horner olefination of aldehydes 1 with N-acyl-2-(diethoxyphosphoryl)glycin ethyl esters 2 to give didehydroamino acid derivatives 3 can be performed advantageously in a 20percent aqueous sodium hydroxide/dichloromethane two-phase system in the absence of any typical phase-transfer catalyst.
N--ΔE-phenylalanine Ethyl Ester
Nitz, Theodore J.,Holt, Elizabeth M.,Rubin, Byron,Stammer, Charles H.
, p. 2667 - 2671 (2007/10/02)
The synthesis of the title compound (1a) has been accomplished by rearrangement of a vinylic isocyanate, and its configuration was confirmed by X-ray crystallography.The configurational stability of 1a to both acids and bases was investigated, and the NMR
