Researchers studying the structures of terpene samples isolated from natural sources often

Researchers studying the structures of terpene samples isolated from natural sources often carry out reaction sequences intended to correlate a new structure with a previously identified one, verifying that the stereochemistry matches. One such sequence that researchers carried out is shown below, starting from -eudesmol and resulting in cryptomeridiol stereoisomers. Fill in the missing structures (one structure per box). -eudesmol OH 1. LiAlH4 2. HO workup 1. LiAlH4 2. HO workup HO cryptomeridiol OH OH HO 4-epi-cryptomeridiol
