摘要:A new steroidal synthesis process is described wherein the steroidal nucleus is provided by a Diels-Alder reaction between a 2,6-lower alkylbenzoquinone and a suitably substituted 1-vinylnaphthalene compound. Depending on the nature of the naphthalene compound it is possible to readily prepare estrones, progesterones, androstanes and cortisones having the natural configuration or if desired having the retro configuration.
