1. A compound of formula II: or a pharmaceutically acceptable salt thereof, wherein: R1 is hydrogen or C1-4 aliphatic, optionally substituted with one or more halogen, —OR, —SR, —N(R)2, —N(R)C(O)R, —C(O)N(R)2, —N(R)C(O)N(R)2, —N(R)C(O)OR, —OC(O)N(R)2, —N(R)SO2R, —SO2N(R)2, —C(O)R, —C(O)OR, —OC(O)R, —S(O)R, or —SO2R; R2 is Hy, where Hy is selected from 4-8 membered saturated or partially unsaturated monocyclic heterocyclic ring having 1-2 heteroatoms independently selected from nitrogen, oxygen, or sulfur, a 5-6 membered monocyclic heteroaromatic ring having 1-4 heteroatoms independently selected from nitrogen, oxygen, or sulfur, or an 8-10 membered bicyclic heteroaromatic ring having 1-5 heteroatoms independently selected from nitrogen, oxygen, or sulfur; R3 is hydrogen, halogen, —CN, —OR, —SR, —N(R)2, —N(R)C(O)R, —C(O)N(R)2, —N(R)C(O)N(R)2, —N(R)C(O)OR, —OC(O)N(R)2, —N(R)SO2R, —SO2N(R)2, —C(O)R, —C(O)OR, —OC(O)R, —S(O)R, —SO2R, —B(OH)2, or an optionally substituted ring selected from phenyl or 5-6 membered heteroaryl having 1-4 heteroatoms independently selected from nitrogen, oxygen, or sulfur; R4 is an optionally substituted phenyl or naphthyl ring; each of R5 and R5′ is independently —R, —OR, —SR, —N(R)2, —N(R)C(O)R, —C(O)N(R)2, —N(R)C(O)N(R)2, —N(R)C(O)OR, —OC(O)N(R)2, —N(R)SO2R, —SO2N(R)2, —C(O)R, —C(O)OR, —OC(O)R, —S(O)R, or —SO2R; or R5 and R5′ are taken together to form a cyclopropylenyl, cyclobutylenyl, or oxetanyl group; each of R7 and R7′ is independently hydrogen, —R, —OR, —SR, —N(R)2, —N(R)C(O)R, —C(O)N(R)2, —N(R)C(O)N(R)2, —N(R)C(O)OR, —OC(O)N(R)2, —N(R)SO2R, —SO2N(R)2, —C(O)R, —C(O)OR, —OC(O)R, —S(O)R, or —SO2R; or R7 and R7′ are taken together to form a 3-8 membered saturated or partially unsaturated monocyclic carbocyclic ring, or a 4-8 membered saturated or partially unsaturated monocyclic heterocyclic ring having 1-2 heteroatoms independently selected from nitrogen, oxygen, or sulfur; and each R is independently hydrogen or an optionally substituted group selected from C1-6 aliphatic, a 3-8 membered saturated or partially unsaturated monocyclic carbocyclic ring, phenyl, an 8-10 membered bicyclic aromatic carbocyclic ring; a 4-8 membered saturated or partially unsaturated monocyclic heterocyclic ring having 1-2 heteroatoms independently selected from nitrogen, oxygen, or sulfur, a 5-6 membered monocyclic heteroaromatic ring having 1-4 heteroatoms independently selected from nitrogen, oxygen, or sulfur, or an 8-10 membered bicyclic heteroaromatic ring having 1-5 heteroatoms independently selected from nitrogen, oxygen, or sulfur. |
