- an optionally substituted alkyl, cycloalkyl, alkenyl, cycloalkenyl, alkynyl, aralkyl, alkaryl, aryl, or heteroaryl group;
- or COR4;
- R1 and R2 may represent atoms necessary to form a five to eight membered ring;
- R3 represents an optionally substituted alkyl, cycloalkyl, alkenyl, cycloalkenyl, alkynyl, aralkyl, alkaryl, aryl, or heteroaryl group;
- R4 represents hydrogen;
- an optionally substituted alkyl, cycloalkyl, alkenyl, cycloalkenyl, alkynyl, aralkyl, alkaryl, aryl, or heteroaryl group;
- OR5;
- or NR6R7;
- R5 represents an optionally substituted alkyl, cycloalkyl, alkenyl, cycloalkenyl, alkynyl, aralkyl, alkaryl, aryl, or heteroaryl group;
- R6 and R7 independently represent hydrogen;
- an optionally substituted alkyl, cycloalkyl, alkenyl, cycloalkenyl, alkynyl, aralkyl, alkaryl, aryl, or heteroaryl group;
- or R6 and R7 may represent atoms necessary to form a five to eight membered ring;
- X represents O , NR8, or CR9R10;
- R8, R9, and R10 independently represent hydrogen;
- or an optionally substituted alkyl, cycloalkyl, alkenyl, cycloalkenyl, alkynyl, aralkyl, alkaryl, aryl, or heteroaryl group;
- R8 and R3 may represent atoms necessary to form a five to eight membered ring;
- and
- any of R3, R9, and R10 may represent atoms necessary to form a five to eight membered ring.
