The reaction of α-tocopherolquinone (3a) and its derivatives (3c,d) with diazomethane was investigated.As the result of its addition to the >C1=O group the spiroepoxycyclohexadienones 5a, b, and c were formed.By catalytic reduction (Pd/C) compound 5a was transformed into the phenol 7.In the presence of BF3*Et2O, compound 5a was cyclized to α-tocopherol (2a).
