Claims (47)

1. A method of synthesizing a chemical compound having chemical formula (I):

wherein R 4 is a carboxylic acid moiety or a derivative thereof, wherein the carboxylic acid moiety or derivative thereof has the chemical formula (II):

wherein the method involves:

reacting a chemical compound having chemical formula (III):

with an acyl chloride having the chemical formula (IV):

under reaction conditions sufficient to form the compound having chemical formula (I), wherein in chemical formula (II) and chemical formula (IV) R 4a are identical and R 4a is a substituted phenyl group, a heteroaryl group, a substituted heteroaryl group,

an amine group, or a substituted amine group,

wherein

the substituted phenyl group is selected from, (i) a trifluoromethylated phenyl group, (ii) a trifluoromethoxy phenyl group, (iii) a phenyl group in which two substituents on the phenyl group are joined together to form an additional 5-7-membered carbocyclic or heterocyclic ring, and (iv) a phenyl group substituted with an alkoxy group, a substituted alkoxy group, an acetamidyl group, an alkoxycarbonyl group, or a substituted heteroaryl-carbonyl group (heteroaryl-O—C(═O)—),

and

wherein in chemical formula (I) and chemical formula (III) R 3a are identical, R 3b are identical, and R 3a and R 3b are each independently a hydrogen atom, an alkyl group, or aryl group.

2. A method according to claim 1 , wherein the substituted heteroaryl group is a substituted pyridine group.

3. A method according to claim 1 , wherein the compound having chemical formula (I) is a compound having chemical formula C(V):

the compound having formula (III) is a compound having chemical formula A(I):

and

the compound having formula (IV) is a compound having chemical formula B(I):

4. A method according to claim 3 , wherein the compound having chemical formula A(I) and the compound having chemical formula B(I) are reacted in the presence of a base selected from triethylamine (Et 3 N) and N,N-diisopropylethylamine (DIPEA).

5. A method of synthesizing a chemical compound having chemical formula C(VI):

wherein the method involves:

reacting a chemical compound having chemical formula A(I):

with an acyl chloride having chemical formula B(I):

under reaction conditions sufficient to form the compound having chemical formula C(VI).

6. A method according to claim 5 , wherein the compound having chemical formula A(I) and the compound having chemical formula B(III) are reacted in the presence of a base selected from triethylamine (Et 3 N) and N,N-diisopropylethylamine (DIPEA).

7. A method according to claim 1 , wherein the compound having chemical formula (I) is a compound having formula C(VII):

the compound having formula (III) is a compound having chemical formula A(I):

and

the compound having formula (IV) is a compound having chemical formula B(IV):

8. A method according to claim 7 , wherein the compound having chemical formula A(I) and the compound having chemical formula B(IV) are reacted in the presence of a base selected from triethylamine (Et 3 N) and N,N-diisopropylethylamine (DIPEA).

9. A method according to claim 1 , wherein the compound having chemical formula (I) is a compound having formula C(XLIII):

the compound having formula (III) is a compound having chemical formula A(I):

and

the compound having formula (IV) is a compound having chemical formula B(VI):

10. A method according to claim 9 , wherein the compound having chemical formula A(I) and the compound having chemical formula B(VI) are reacted in the presence of a base selected from triethylamine (Et 3 N) and N,N-diisopropylethylamine (DIPEA).

11. A method of synthesizing a chemical compound having chemical formula C(I):

wherein the method involves:

reacting a chemical compound having chemical formula A(I):

with an acyl chloride having chemical formula B(VII):

under reaction conditions sufficient to form the compound having chemical formula C(I).

12. A method according to claim 11 , wherein the compound having chemical formula A(I) and the compound having chemical formula B(VII) are reacted in the presence of a base selected from triethylamine (Et 3 N) and N,N-diisopropylethylamine (DIPEA).

13. A method according to claim 1 , wherein

the compound having chemical formula (I) is a compound having formula C(XX):

the compound having formula (III) is a compound having chemical formula A(I):

and

the compound having formula (IV) is a compound having chemical formula B(VIII):

14. A method according to claim 13 , wherein the compound having chemical formula A(I) and the compound having chemical formula B(VII) are reacted in the presence of a base selected from triethylamine (Et 3 N) and N,N-diisopropylethylamine (DIPEA).

15. A method according to claim 1 , wherein the alkoxycarbonyl group is a methoxycarbonyl (CH 3 OC(═O)—).

16. A method according to claim 2 , wherein the substituted pyridine group is selected from (i) an O-alkylated pyridine group, (ii) an O-arylated pyridine group, and (iii) a halogenated pyridine group.
