Claims (670)

1. A compound of formula I′:

or a pharmaceutically acceptable salt thereof, wherein:

X is N or C(R 3 );

R 1 is —CH 2 F, —CHF 2 , —NRR D , —N(R D ) 2 , or —OR D ;

R 3 is H, halogen, or C 1-6 aliphatic; or

R 2 and R 3 are taken together with their intervening atoms to form a 4-7 membered partially unsaturated or aromatic ring having 0-3 heteroatoms independently selected from nitrogen, oxygen, and sulfur; wherein said ring is substituted with m instances of R 4 ;

each of Cy 1 and Cy 2 is independently phenyl; a 5-6 membered monocyclic heteroaryl ring having 1-4 heteroatoms independently selected from nitrogen, oxygen, and sulfur; an 8-10 membered bicyclic heteroaryl ring having 1-4 heteroatoms independently selected from nitrogen, oxygen, and sulfur; a 3-7 membered saturated or partially unsaturated heterocyclic ring having 1-2 heteroatoms independently selected from nitrogen, oxygen, and sulfur; or a 3-7 membered saturated or partially unsaturated monocyclic carbocyclic ring; or a 7-12 membered saturated or partially unsaturated bicyclic heterocyclic ring having 1-4 heteroatoms independently selected from nitrogen, oxygen, and sulfur, wherein Cy 1 is substituted with n instances of R 5 ; and; wherein Cy 2 is substituted with p instances of R 6 ;

L 1 is a covalent bond or a C 1-4 bivalent saturated or unsaturated, straight or branched hydrocarbon chain wherein one or two methylene units of the chain are optionally and independently replaced by C(R 7 ) 2 —, N(R)—, —N(R)C(O)—, —C(O)N(R)—, —N(R)S(O) 2 —, —S(O) 2 N(R)—, —O—, —C(O)—, —OC(O)—, —C(O)O—, —S—, —S(O)— or —S(O) 2 —;

each instance of R 4 , R 5 , R 6 , and R 7 is independently R A or R B , and is substituted by q instances of R C ;

each instance of R A is independently oxo, halogen, —CN, —NO 2 , —OR, —OR D , —SR, —NR 2 , —S(O) 2 R, —S(O)(NR)R, —S(O) 2 NR 2 , —S(O)R, —S(O)NR 2 , —C(O)R, —C(O)OR, —C(O)NR 2 , —C(O)N(R)OR, —OC(O)R, —OC(O)NR 2 , —N(R)C(O)OR, —N(R)C(O)R, —N(R)C(O)NR 2 , —N(R)C(NR)NR 2 , —N(R)S(O) 2 NR 2 , —N(R)S(O) 2 R, —N(R D )S(O) 2 R, —N(R)S(O) 2 R D , —N(R D )S(O) 2 R D , or —P(O)R 2 ;

each instance of R B is independently C 1-6 aliphatic; phenyl; a 5-6 membered monocyclic heteroaryl ring having 1-4 heteroatoms independently selected from nitrogen, oxygen, and sulfur; an 8-10 membered bicyclic heteroaryl ring having 1-4 heteroatoms independently selected from nitrogen, oxygen, and sulfur; a 3-7 membered saturated or partially unsaturated carbocyclic ring; a 3-7 membered saturated or partially unsaturated monocyclic heterocyclic ring having 1-2 heteroatoms independently selected from nitrogen, oxygen, and sulfur; or a 7-12 membered saturated or partially unsaturated bicyclic heterocyclic ring having 1-4 heteroatoms independently selected from nitrogen, oxygen, and sulfur;

each instance of R c is independently oxo, halogen, —CN, —NO 2 , —OR, —SR, —NR 2 , —S(O) 2 R, —S(O) 2 NR 2 , —S(O)R, —S(O)NR 2 , —C(O)R, —C(O)OR, —C(O)NR 2 , —C(O)N(R)OR, —OC(O)R, —OC(O)NR 2 , —N(R)C(O)OR, —N(R)C(O)R, —N(R)C(O)NR 2 , —N(R)C(NR)NR 2 , —N(R)S(O) 2 NR 2 , or —N(R)S(O) 2 R or an optionally substituted group selected from C 1-6 aliphatic, phenyl, a 3-7 membered saturated or partially unsaturated heterocyclic ring having 1-2 heteroatoms independently selected from nitrogen, oxygen, and sulfur, and a 5-6 membered heteroaryl ring having 1-4 heteroatoms independently selected from nitrogen, oxygen, and sulfur;
