.  [^0]: ^a^Data were measured in MeOD-*d*~0~ at 000 MHz for ^0^H NMR and 000 MHz for ^00^C NMR. The *δ* values are expressed in ppm and the coupling constants (*J*) in Hz. The assignments were made on the basis of DEPT, ^0^H---^0^H COSY, HSQC and HMBC results.  [^0]: ^a^Data were measured in MeOD-*d*~0~ at 000 MHz for ^0^H NMR and 000 MHz for ^00^C NMR.
