Claims17
A compound of the general formula I
- 6
- wherein
- R1 and R2 independently are CH2, CH3, CHCH3, or CH2CH3;
- R3 is H, CH3, or CH2CH3;
- R4, R5, R6, and R7 independently are H or CH3;
- with the proviso that R4, R5, R6, and R7 are not all hydrogen, and where the dashed line represents a single bond, or one of the bonds R1-C5, C5-C6 or C6- R2 represents a double bond.
