A series of 2 amimo 3 cyano 7,7 dimethyl 4 aryl 5 oxo 5,6,7,8 tetra 4H chromenes were synthesized in the absence of catalyst. Their structures were determined by IR, 1H NMR, and single crystal X ray diffraction.
The structure of N -(4-chlorobenzyl)-2,3-methenedioxy-9-acetoxyl-10-methyloxyl-7,8,13,13a-tetrahydro-8H-dibenzo-quinolizine chloride has been studied with IR, MS, HRMS and NMR( 1HNMR, 13 CNMR, COSY, HETCOR).
