Claims15
A method for preparing an acylated cyclic product of Formula 1
- 68
- wherein
- A is a linking group comprising an optionally substituted backbone segment consisting of 2 to 4 atoms selected from carbon atoms and 0 to 2 nitrogen, 0 to 2 oxygen and 0 to 2 sulfur atoms;
- J is an optionally substituted, carbon-linked hydrocarbyl group;
- and
- Y is H or a salt cation;
- the process comprising contacting a phenyl ester of Formula 2
- 69
- wherein
- y is 0, 1, 2 or 3;
- and
- each R is independently selected from electron-withdrawing groups;
- with a cyclic compound of Formula 3
- 70
- in the presence of a source of cyanide or fluoride ion.
