Patent ID: 8252808

Claim:
A compound having a formula (Ia): wherein: R 3 is selected from the group consisting of hydrogen, {−}C(O)R 6 , and {−}R 6 ; R 5 is selected from the group consisting of alkyl having from 1 to 8 carbons, CH 3 CHCl—{−} and CH 2 ═CH—{−}; R 6 is selected from the group consisting of hydrocarbyl and hydrocarbyl substituted with at least one atom other than carbon; R 8 and R 9 are independently selected from the group consisting of hydrogen, hydroxyl, hydrocarbyl, and hydrocarbyl substituted with at least one atom other than carbon, or R 8 and R 9 together form a carbonyl group; R 12 and R 13 are independently selected from the group consisting of hydrogen, hydrocarbyl, and hydrocarbyl substituted with at least one atom other than carbon, or R 12 and R 13 together form a carbonyl group; and R 10 , R 11 , and R 14 are independently selected from the group consisting of hydrogen, hydrocarbyl, hydrocarbyl substituted with at least one atom other than carbon, and a halogen.
