Step-by-Step Synthesis of Unsymmetrically Substituted Pyranoisocoumarins from Terephthalic Acid
An efficient multi-step protocol for the selective synthesis of unsymmetrically substituted pyranoisocoumarins (pyrano[3,4-g]isochromene-1,6-diones) has been developed. The procedure includes the two-fold step-by-step C–H annulation of terephthalic acid with two different alkynes. The photophysical properties of pyranoisocoumarins were predicted by DFT calculations.
