In an analogous fashion to the preparation of ergosterol peroxide from singlet oxygen, the preparation of its sulfur analog was attempted via the Diels-Alder addition of diatomic sulfur to ergosterol. Two of the recently reported methods for generating and trapping diatomic sulfur were employed as well as" activated" sulfur. Although the desired target was not obtained, several interesting steroidal products were isolated including 3, 5-cyclo-6, 8 (14) ...
