A compound of Formula (I)
- wherein
- each R1 is independently hydrogen, halo, alkyl, aryl, alkaryl, or aralkyl;
- each R2 is independently hydrogen, alkyl, alkoxy, aryl, alkaryl, aralkyl, hydroxyl, silyloxy, combines with a R3 connected to a same carbon atom to form a cyclic alkyl, combines with a R3 connected to the same carbon atom to form a cyclic alkyl that is fused to one or more carbocyclic rings, or combines with R3 and the carbon atom to which both R2 and R3 are connected to form a carbonyl group;
- each R3 is independently hydrogen, alkyl, alkoxy, aryl, alkaryl, aralkyl, hydroxyl, silyloxy, combines with a R2 connected to a same carbon atom to form a cyclic alkyl, combines with a R2 connected to the same carbon atom to form a cyclic alkyl that is fused to one or more carbocyclic rings, combines with R2 and the carbon to which both R2 and R3 are connected to form a carbonyl group, or combines with R4 connected to adjacent carbon atom to form a carbon-carbon bond;
- and
- each R4 is independently hydrogen or combines with R3 connected to an adjacent carbon atom to form a carbon-carbon bond.
