Synthesis of nitroaryl derivatives of glycine via oxidative nucleophilic substitution of hydrogen in nitroarenes
Ma?kosza, Mieczys?aw,Chromi?ski, Miko?aj,Sulikowski, Daniel
experimental part, p. 82 - 91 (2011/06/20)
Carbanion of ethyl N-(1,3-dithiolan-2-ylidene)glycinate adds to activated nitroarenes mostly in para position to the nitro group. Subsequent oxidation of the resulting σH adducts with DDQ gave respective α-nitroarylated glycine derivatives in moderate yields. The reaction of esters of chiral alcohols such as (-)-menthol or (-)-8-phenylmenthol proceeds with a moderate or high diastereoselectivity leading to enantiomerically enriched nitroarylglycines.

Enantiopure fluorinated prolines with four chiral centers were obtained from 1,3-dipolar cycloaddition of azomethine ylides and (E)-ethyl 3-fluoroacrylate. Georg Thieme Verlag Stuttgart.
Synthesis and biological evaluation of menthol-based derivatives as inhibitors of plasminogen activator inhibitor-1 (PAI-1)
Ye, Bin,Bauer, Shawn,Buckman, Brad O.,Ghannam, Ameen,Griedel, Brian D.,Khim, Seock-Kyu,Lee, Wheeseong,Sacchi, Karna L.,Shaw, Kenneth J.,Liang, Amy,Wu, Qingyu,Zhao, Zuchun
, p. 3361 - 3365 (2007/10/03)
Compound 1 was identified by high throughput screening as a novel PAI-1 inhibitor. Optimization of the B and C-segments of 1 resulted in a series of structurally simplified compounds with improved potency. The synthesis and SAR data of these compounds are presented here.
Synthesis and biological activities of conformationally restricted cyclopentenyl-glutamate analogues
Ung, Alison T.,Schafer, Karl,Lindsay, Karl B.,Pyne, Stephen G.,Amornraksa, Kitti,Wouters, Ria,Van der Linden, Ilse,Biesmans, Ilse,Lesage, Anne S.J.,Skelton, Brian W.,White, Allan H.

An efficient method for preparing conformationally restricted cyclopentenyl-glutamate analogues in a regioselective and diastereoselective manner has been developed using a formal [3 + 2] cycloaddition reaction of dehydroamino acids. Methods for preparing optically active versions of these compounds have also been devised. Of these compounds, (S)-2 is an agonist at the mGlu5 (EC50 18 μM) and mGlu2 (EC50 45 μM) receptors.
A radical-organometallic glycine synthon. Preparation of homochiral heterocyclic α-amino acids
Lloris,Moreno-Manas
, p. 7119 - 7122 (2007/10/02)
Co(Acac)2 reacts with (1) and (d)-menthyl N-BOC-2-bromoglycinates to give (1)- and (d)-menthyl N-BOC-3-acetylnorvalinates, which are converted into homochiral 2-(3,5-dimethyl-4-pyrazolyl)glycine and 2-(3,5-dimethyl)-4-isoxazolylglycine.
The asymmetric synthesis of α-amino acids via the addition of grignard reagents to imine derivatives
Hamon, David P. G.,Massy-Westropp, Ralph A.,Razzino, Pasquale
, p. 5163 - 5178 (2007/10/02)
The ester-8-phenylmenthyl N-Boc-glycinate 5a, undergoes free radical bromination by N-bromosuccinimide to give 8-phenylmenthyl N-Boc-bromoglycinate 8. Treatment of the bromide 8 with a variety of Grignard reagents at low temperature gave 8-phenylmenthyl (S-N-Boc-2-alkylgrycinates with high diastereoselectivity. Conditions were found for the hydrolysis of these derivatives with no racemization of the resultant amino acid.
