Thermal -Sigmatropic Hydrogen Shifts: Stereochemistry, Kinetics, Isotope Effects, and ?-Facial Selectivity

The antarafacial stereochemistry of the thermal -sigmatropic hydrogen shift has been demonstrated.The substrates studied include the epimeric cis-isotachysterol analogues 1 and 4 and their stereospecifically 15α-deuterium-labelled derivatives 7 and 1
