Abstract

The present invention provides compounds, compositions thereof, and methods of using the same.

Claims (20)

1 . A SMARCA2 inhibitor compound of formula II-a-3:

or a pharmaceutically acceptable salt thereof, wherein:

each of Ring B and Ring D is independently a fused ring selected from 6-membered aryl, 5 to 6-membered heteroaryl containing 1-4 heteroatoms independently selected from nitrogen, oxygen, and sulfur, and a 4 to 9-membered saturated or partially unsaturated monocyclic, bicyclic, or bridged bicyclic carbocyclyl or heterocyclyl with 1-4 heteroatoms independently selected from boron, nitrogen, oxygen, silicon, and sulfur;

each R 2 is independently hydrogen, R 4 , halogen, —CN, —OR, —NR 2 , —CFR 2 , —CF 2 R, —CF 3 , —C(O)R, —C(O)OR, or —C(O)NR 2 ;

each R 3 is independently fluoro or chloro;

each R is independently hydrogen, or an optionally substituted group selected from C 1-6 aliphatic, phenyl, a 4-7 membered saturated or partially unsaturated heterocyclic 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, or:

two R groups on the same atom are taken together with their intervening atoms to form a 4-7 membered saturated, partially unsaturated, or heteroaryl ring having 0-3 heteroatoms, in addition to the atom to which they are attached, independently selected from nitrogen, oxygen, and sulfur;

each R 4 is independently an optionally substituted group selected from C 1-6 aliphatic, phenyl, a 4-7 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;
