N-Cinnamoyl-l-phenylalanine methyl ester
As part of an ongoing investigation into the development of N-substituted amino acids as building blocks for dynamic combinatorial chemistry, we report the structure of the title compound, C(19)H(19)NO(3). This compound crystallizes as discrete mol-ecules. The cinnamoyl group is non-planar, with the phenyl ring and the amide twisted out of the ethyl-ene plane. The benzyl and ester groups lie ab...
متن کاملN-{N-[N-(1,1-Dimethylethoxycarbonyl)-l-leucyl]-N-methyl-l-leucyl}-N-methyl-l-leucine benzyl ester
The tripeptide title compound, C(32)H(53)N(3)O(6), synthesized in 80% yield by coupling of N-methyl-l-leucine benzyl ester with tert-butoxy-carbonyl-l-leucyl-N-methyl-l-leucine at 273 K, conjugates through two amide linkages and includes two protecting groups: a tert-butyl-oxycarbonyl group at the C-tip and a benzyl group at the N-tip. A classical inter-molecular N-H⋯O hydrogen bond and a weak ...
متن کاملl-Serine methyl ester hydrochloride
In the enanti-opure crystal of the title compound, C(4)H(10)NO(3) (+)·Cl(-), inter-molecular O-H⋯Cl and N-H⋯Cl hydrogen bonds link the mol-ecules into layers parallel to (001).
متن کاملl-Alanine methyl ester hydrochloride monohydrate
The enanti-opure title compound, C(4)H(10)NO(2) (+)·Cl(-)·H(2)O, forms a two-dimensional network by inter-molecular hydrogen bonding parallel to (010). Non-merohedral twinning with a twofold rotation about the reciprocal c* axis as twin operation was taken into account during intensity integration and structure refinement. This twinning leads to alternative orientations of the stacked hydrogen-...
متن کاملStandard Thermodynamic Functions of Tripeptides N-Formyl-l-methionyl-l-leucyl-l-phenylalaninol and N-Formyl-l-methionyl-l-leucyl-l-phenylalanine Methyl Ester
The heat capacities of tripeptides N-formyl-l-methionyl-l-leucyl-l-phenylalaninol (N-f-MLF-OH) and N-formyl-l-methionyl-l-leucyl-l-phenylalanine methyl ester (N-f-MLF-OMe) were measured by precision adiabatic vacuum calorimetry over the temperature range from T = (6 to 350) K. The tripeptides were stable over this temperature range, and no phase change, transformation, association, or thermal d...
