Abstract Nine new chromene amides derived from tyramine together with known chromene amides, coumarins and furoquinolines have been isolated from roots of Amyris texana. The structures of the new amides were determined by spectroscopic data and synthesized starting from tyramine. The equilibrium distribution of the syn and anti isomers of the tertiary amides was solvent-dependent. The 13 C and 1 H NMR (LIS and ASIS) data suggested ...
