标题:An Efficient Synthesis Of [ring-14C]-L-Tyrosine From [u-14C]-Phenol
摘要:The Title Compound Was Prepared In Good Overall Yield And High Enantiopurity Via A Five Step Route Beginning With [u-C-14]-Phenol,4. Benzyl Ether 5 Was Prepared From 4 Under Standard Conditions And Underwent Selective Iodination At The 4-Position In The Presence Of Iodine And Mercuric Oxide. Palladium Catalysed Cross Coupling Of The Resulting Aryl Iodide 6 And The Organozinc Intermediate Derived From N-Tert-Butoxycarbonyl-3-Iodo-Alanine Methyl Ester,7,Proceeded Smoothly To Give 8. Debenzylation And Acid Hydrolysis Afforded The Deprotected Amino Acid As The Hydrochloride Salt. Purification (Flash Chromatography) Was Necessary In Only Two Of The Five Steps In The Synthesis.

标题 :N-protected-α-amino acid compounds
发明人：VEBER DANIEL F; BRADY STEPHEN F
权利人:MERCK & CO INC
摘要:Novel N-protected-α-amino acid compounds are disclosed in which the amino functionality is protected by a 1-methylcyclobutyloxycarbonyl or 1-methylcyclohexyloxycarbonyl. Processes for the synthesis of amino acids containing these protecting groups and the use of these novel amino acid compounds in the preparation of peptides are also disclosed.

标题 :Labelled cardiotonic glycosides for use in radioimmunoassay
发明人：COOMBES ROBERT F
权利人:CURTIS NUCLEAR CORP
摘要:Disclosed are radioactive cardiotonic glycosides and a process of making such glycosides, the compounds being useful for radioimmunoassay of body fluids for cardiotonic glycoside content. n The novel synthesis comprises reaction of a hydroxyl group of the sugar with a dicarboxylic acid derivative such as a diacid, diacid anhydride or a diacyl halide and thereafter reacting the free carboxylic group with a compound which will undergo electrophilic substitution reactions. A radioactive isotope, preferably 125 I, is reacted via electrophilic substitution with the compound to form the radioactive cardiotonic glycoside.
