Menthyl ester 11 was obtained in 66% overall yield by esterification of 2-chloropropionic acid with (1R,2S,5R)-(-)-menthol in benzene under tosic acid catalysis, followed by LDA-mediated deprotonation of the resulting ester in THF at -78°C and reaction of the anionic species with PhSeBr. Analogously, 2 was prepared from commercially available ethyl 2-chloro propionate; see
