cis- And trans-2,2-dimethyl-4-carbomethoxy-5-phenylthiazolidines prepared from the corresponding erythro- and threo-β-phenylcysteines were resolved into the enantiomers by use of a chiral HPLC column, from which all of the four chiral β-phenylcysteine met
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
THE SYNTHESES OF N-FREE α-DEHYDROAMINO ACID ESTERS AND N-ACETYL DEHYDRODIPEPTIDE ESTER FROM N-CARBOXY α-DEHYDROAMINO ACID ANHYDRIDE

, p. 1635 - 1638 (2007/10/02)
N-Carboxy α-dehydroamino acid anhydride, derived from N-benzyloxycarbonyl α-dehydroamino acid (DHA) and thionyl chloride, was found to be very useful for the synthesis of N-free DHA ester by alcoholysis and N-acetyl dehydrodipeptide ester by coupling was
The Preparation and Reactions of 2-Benzyloxy-4-benzylideneoxazol-5-one
Jones, John H.,Witty, Michael J.
, p. 858 - 864 (2007/10/02)
The preparation of the title coumpound (4) and a survey of its chemistry are described.Its reactivity towards nucleophiles at C-5 is high compared with that of the corresponding 2-phenyl compound (1), and nucleophilic reagents attact (4) exclusively at th
