| 1 | The Synthesis of Cyclic Amino Acids显示文摘Several cyclic amino acids(1-4)were synthesizedfrom glycine.Isocyanate ester wasprepared asthe keyintermediate and reacted with dibromoalkanesto affordthetarget compounds. | Shrong Shi LIN | 2003 | Chinese Chemical Letters2003，14，9： | 2 |
| 2 | The Synthesis of a Novel Phosphorus Containing Antigen显示文摘Antigen 12, containing a phosphonyl peptide hapten with free C-terminal carboxylic group, was synthesized by 11 reaction steps. The design of the hapten was based on the transition state of peptide hydrolysis catalyzed by carboxypeptidase A. | Gui Yang XIE, Jia Hua CHEN*, Shrong Shi LIN, Sheng JIN Ministry of Education Key Lab of Bioorganic Chemistry &Molecular Engineering, College of Chemistry and Molecular Engineering, Peking University, Beijing 100871 | 2001 | Chinese Chemical Letters2001，12，6： | 1 |
| 3 | The Synthesis of 4-Arylcarbonyl-3-methoxycarbonyl-2-phenylfurans by Friedel-Crafts Acylation Reactions显示文摘Keto esters 8, 4-arylcarbonyl-3-methoxycarbonyl potential precursors of the synthesis of furofuran lignans, were obtained from dimethyl 2-phenylfuran- 3,4dicarboxylate 2. Diester 2 was selectively hydrolyzed to monoacid 6 followed by converting to its acid chloride 7. Friedel-Crafts acylation reactions of 7 with aromatic compounds afforded keto esters 8. The geometric structures of 8 and its precursors were elucidated and verilied by NMR spectra. | Shrong Shi LIN Jun Hua YU Jian Mei WANG Bo YANG Xiu Lin YE (Department of Chemistry.

| 4 | Preparation and Reactions of Pyridinium Ylids via Decarboxylation of Pyridinium Betaines显示文摘Pyridinium ylids 4 were generated as reaction intermediates from the decarboxylation of pyridinium betaines 3, which were prepared from the reactions of a-amino acid ester hydrochlorides with 2, 4, 6-triphenylpyrylium tetrafluoroborate. Protonation, addition and substitution reactions of 4 with electrophiles were studied in this paper. | Shrong Shi LIN*, Jian Mei WANG, Xuan WANG, Cheng Yong LI College of Chemical and Molecular Engineering, Peking University, Beijing 100871 | 2002 | Chinese Chemical Letters2002，13，7： | 0 |
| 5 | Efficient Synthesis of 2,6-Diphenyl-4-arylpyrylium Tetrafluoroborate显示文摘Four pyrylium salts, (2,6-diphenyl-4-arylpyrylium tetrafluoroborate, aryl = C6H5, 4-MeO C6H4, 4-Me2NC6H4, 4-NO2C6H4) were synthesized efficiently and economically from acetophenone and substituted chalcones in the presence of borontrifluoride. | Shrong Shi LIN*, Cheng Yong LI, Xuan WANG Department of Chemistry, Peking University, Beijing 100871 | 2002 | Chinese Chemical Letters2002，13，7： | 0 |
| 6 | The Synthesis and Regioselective Hydrolysis of Dialkyl 2-Phenylfuran (and 2-Phenyltetrahydrofuran) -3,4-dicarboxylates显示文摘Dialkyl 2-phenylfuran (and 2-phenyltetrahydrofuran)-3,4-dicarboxylates (1, 2, 5-7), which are potential precursors of the synthesis of furofuran and tetrahydrofurofuran lignans, can be selectively hydrolyzed to monoacid (3, 8) by potassium hydroxide. The regioselective hydrolysis was affected significantly by the 2-phenyl group of the furan or tetrahydrofuran skeleton. The geometric structures of 3, 8 and related compounds were elucidated and verified by NMR spectra. | Shrong Shi LIN*, Bo YANG College of Chemical and Molecular Engineering, Peking University, Beijing 100871 | 2002 | Chinese Chemical Letters2002，13，9： | 0 |
| 7 | The Reactivity of 2,4,6-Tirphenylpyridinium Ylids显示文摘Triphenylpyridinium ylid 2, generated by the decarboxylation of betaine 1, were noted to react with acetyl chloride, chloroform or acetone to form addition-elimination product and proton extraction - carbanion addition products, respectively. The reaction with chloroform was determined as pseudo first order from kinetic experiments. The values of kobsd and t1/2 for decarboxylation at 20, 40 and 50C were calculated to be 4.6 x 10-4, 8.8 x 10-3, 2.8 x 10-2 min-1 and 1.5 x 103, 78, 24 minutes, respectively. | Shrong Shi LIN*, Jian Mei WANG, Cheng Yong LI Department of Chemistry, Peking University, Beijing 100871 | 2003 | Chinese Chemical Letters2003，14，2： | 0 |
| 8 | The Studies of the Reactions of 2,4,6-Triphenylpyrylium Tetrafluoroborate with Amino Acids显示文摘The reactions of triphenylpyrylium salt 1 with various amino acids were explored andcompared. The reactions with most α-amino acids yielded decarboxylation products 2 viadecarboxylation. The reactions with glutamic acid, lysine and ACC (1-aminocyclopropyl-carboxylic acid) gave triphenylpyridine 8, dimer 9 and acid 5a-acc, respectively. The reactionswith β and γ-amino acids yielded triphenylpyridine by intramolecular elimination. | Shrong Shi LIN | 2003 | Chinese Chemical Letters2003，14，9： | 0 |
| 9 | Spectral and Mechanistic Studies of the Reactions of Substituted 1,5-Benzothiazepine with Dichloroacetyl Chloride and Triethylamine显示文摘A [2+2] cycloaddition adduct 2 and a novel ring-opening product 3 were obtained from the reactions of 2,3-benzothiazepines 1 with dichloroacetyl chloride and triethylamine. The relative ratios of 2 and 3 were affected by the addition order of reactants and reaction temperature. The structures were determined by spectral data and the reaction mechanisms for the formation of 2 and 3 were elucidated. | Xin ZHOU Shrong Shi LIN Jin Fang YUAN Zhe Ming WANG Hong Zhong WANG | 2001 | Chinese Chemical Letters2001，12，10： | 0 |
