Web4.2. Make: C3–C9, C6–O15. Break: C3–O4, C3–C6, O7–Ts8, C9–O10. Note the somewhat unusual cleavage of the O7–Ts8 bond. 8 NaOMe is a base as well as a nucleophile, and OTs is a leaving group, so the –OMe can promote E2 elimination of HOTs. (Either OTs group can be eliminated.) MeO– can then attack Ts8 to cleave the C7–Ts8 bond ...
