  Substituent Effects On Intramolecular Epoxide Cyclizations That Can Competitively Occur at Aromatic or Double Bond Positions¹

  摘要：

  The effects of substituents on epoxides that can competitively cyclize at either a double bond or aromatic position were determined. Adding a group that would stabilize the transition state of the double bond cyclization of an epoxide that underwent predominantly aromatic cyclization increased the relative amount of the former pathway, but not dramatically. Adding a strong activating substituent to the aromatic group of an epoxide that underwent predominantly double bond cyclization increased the relative amount of aromatic cyclization, but a complex product mixture was obtained. An explanation of the behavior observed is presented.

  stereospecificity. Cyclization of similar substrates with an alkyl substituent in the appropriate position gave exclusively 11α-alkyl derivatives of 8a and 9a. The products were converted into the corresponding 13α,17α-epoxides by peracid oxidation and hence into derivatives of 8α-estrone and 8α-estradiol. 11α-Methyl-8α-estra-1,3,5(10)-triene-3,17(3-diol (16b) was obtained in its two enantiomeric forms
