How is Cyano(3-phenoxyphenyl)methyl (1R,3R)-2,2-dimethyl-3-(2-methyl-1-propen-1-yl)cyclopropanecarboxylate (CAS: 39515-40-7) typically synthesized?

Cyano(3-phenoxyphenyl)methyl (1R,3R)-2,2-dimethyl-3-(2-methyl-1-propen-1-yl)cyclopropanecarboxylate can be synthesized via a multi-step reaction involving protection of the phenol group, formation of the cyclopropanecarboxylic acid, and subsequent formation of the ester. Commonly, this involves the use of protecting groups, esterification, and hydrogenation steps. The reaction typically yields about 75-85% of the target product with good selectivity.
