Ak. Banerjee et al., Synthesis of an intermediate for (+/-)-platphyllide through thionyl chloride-pyridine mediated rearrangement, SYN COMMUN, 29(17), 1999, pp. 2995-3001
The cyclohexadienyl alcohol (3) on treatment with thionyl chloride and pyri
dine provided the tetrahydronaphthalene (4) whose transformation to the car
bomethoxy tetralone (7), a key intermediate for platphyllide (8), has been
accomplished in four steps.
