Approaches to the Synthesis of Ring C Transposed Progesterone Analogues.rac-7β,15α-Ethano-11,12-seco-11,19-bisnor-17α-pregn-4-ene-3,20-dione and rac-4,4-dimethyl-7,7-(ethylenedioxy)-(4aα,4bβ,8aα,10aβ)-perhydro-3-phenanthrenone

In an approach to the synthesis of ring C transposed progesterone derivatives rac-4,4-dimethyl-7,7-(ethylenedioxy)-(4aα,4bβ,8aα,10aβ)-perhydro-3-phenanthrenone (30) and rac-7β,15α-ethano-11,12-seco-11,19-bisnor-17α-pregn-4-ene-3,20-dione (28) have been synthesized from 6-methoxytetralone.The structure of 28 has been established by X-ray crystallographic analysis.
