Answer
Elements of unsaturation:
Parsalmide - 7 unsaturations
Ethynyl estradiol - 9 unsaturations
Dynemicin A - 22 unsaturations
Work Step by Step
Each pi bond and each ring is 1 element of unsaturation.
Parsalmide - 4 double bond+ 1 triple bond+ 1 ring = 7 unsaturations
Ethynyl estradiol - 3 double bond + 1 triple bond + 4 rings = 9 unsaturations
Dynemicin A - 11 double bond + 2 triple bond + 7 rings = 22 unsaturations
