a) S=c1[nH]nc(-c2cc(-c3ccccc3)n[nH]2)n1/N=C/C=C/c1ccccc1
b) CC(C)C(=O)NC(=S)/C=C1/N(C)c2ccccc2C1(C)C
c) O=C(Nc1ccccn1)NC1CCS(=O)(=O)C1
d) COCc1cc(CN2CCCC(C(=O)c3cccc(C(F)(F)F)c3)C2)ccc1OC
e) Cc1cccc(-n2ncc3c2CCCC3NC(=O)CCN2Cc3ccccc3C2=O)c1C
Answer: a. S=c1[nH]nc(-c2cc(-c3ccccc3)n[nH]2)n1/N=C/C=C/c1ccccc1
