| dc.description.abstract | First total synthesis of (±)-maxima flavanone A (1) and the synthesis of other 6-prenylpyranoflavanones 2 and 7 has been described from pyranoacetophenone 10. The acetophenone 10 on reaction with prenylbromide in DMF solution, in presence of K2CO3 gives the prenylether 11 which on heating in N,N-dimethylaniline at 160-170 °C undergoes Claisen and Cope rearrangements providing the pyranoacetophenone 12. Condensation of 12 with aryl aldehydes using methanolic KOH as base in the presence of CTAB gives the chalcones 13a-c, which on cyclisation using KF-Celite in refluxing methanol yield the angular pyranoflavanones 1,2 and 7, respectively. | en_US |
