Assignment of the 13C-nmr spectrum of Hippurin, a novel furospirostane: observation of both ends of the axis of anisotropic reorientation through the measurement of spin-lattice relaxation times.
Anisotropic reorientation of 3 alpha-substituted steroids has been well documented. Assignment of the 13C-nmr spectrum of Hippurin, a novel furospirostane and the measurement of the spin-lattice (T1) relaxation times has established both points in the molecule through which the axis of anisotropic reorientation passes, specifically the 3- and 24-positions.
