(1S,3S)-1-tert-Butyl­diphenyl­siloxy-3-hydr­oxy-3-isopropenyl-1,2,3,4-tetra­hydro­naphthalene

In the title compound, C₂₉H₃₄O₂Si, the isopropenyl group is oriented trans and the OH group is cis to the tert-butyl­diphenyl­siloxy (OTBDPS) group. The cyclo­hexane ring of the tetra­hydro­naphthalene system adopts a half-chair conformation in which the stereogenic centre at the ring C3 atom is projected above the plane of the ring (³H₂), minimizing steric congestion between the substituents on the ring C3 atom and the bulky OTBDPS group.
