摘要:
The present invention relates to a process of manufacturing (6R,10R) -6,10,14-trimethylpentadecan-2-one in a multistep synthesis from 6,10- dimethylundeca-3,5,9-trien-2-one. The process is very advantageous in that it forms in an efficient way the desired chiral product from a mixture of stereoisomers of the starting product.
摘要:
The invention relates to an improved process for the manufacture of bis-resorcinyl triazines of formula (I) wherein R 1 is a C 1 C 18 alkyl group or C 2 -C 18 alkenyl group as well as the respective alkyl substituted bis-resorcinyl derivatives of formula (II) wherein R 1 is a C 1 -C 18 alkyl group or C 2 -C 18 alkenyl group and R 2 and R 3 are independently of each other a C 1 -C 18 alkyl group or a C 2 -C 18 alkenyl group.
