Abstract/OtherAbstract:
N-Isobutylidenedipivalamide, C14H28N2O2, Mr = 256.39, orthorhombic, P2(1)2(1)2(1), a = 16.656 (2), b = 9.751 (2), c = 10.583 (2) A, V = 1718.8 A3, Z = 4, D chi = 0.99 g cm-3, lambda(Cu K alpha) = 1.5418 A, mu = 4.56 cm-1, mu Rmax much less than 1, F(000) = 568, T = 293 K, R = 0.081 for 887 observed reflections. The geometrical parameters of this retro-peptide molecule are quite similar to the standard values for peptides. Conformational angles are phi = -101 (1), phi' = 99 (1) degrees.
