or R 3 and R 1 are taken together with their intervening atoms to form an optionally substituted saturated or unsaturated 12-18 membered ring having 2-6 heteroatoms independently selected from nitrogen oxygen, or sulfur, wherein the ring formed thereby comprises -L-Y; or
R 3 and a ring formed by R 1 and R 1 , are taken together with their intervening atoms to form an optionally substituted saturated or unsaturated 12-18 membered ring having 2-6 heteroatoms independently selected from nitrogen oxygen, or sulfur, wherein the ring formed thereby comprises -L-Y;

R 4 is H, —NHC(O)R 5 , —NHC(O)OR 6 ,

 or a natural or unnatural amino acid side-chain group;
each R 5 is independently —N(R) 2 or an optionally substituted group selected from C 1-6 aliphatic, a bridged bicyclic, 6-10 membered aryl, 5-10 membered heteroaryl having 1-4 heteroatoms independently selected from nitrogen, oxygen, or sulfur, or 4-7 membered heterocyclyl having 1-2 heteroatoms independently selected from nitrogen, oxygen, or sulfur;
