摘要
As part of continuing studies on the synthesis of new, biologically interesting 11-beta-substituted steroidal spirolactones, we describe here the competition between 10-beta-propargylation and 11-beta-allenylation. Grignard addition of allenyl magnesium bromide to an appropriate 5,10-epoxy-9(11)-olefin provides 10-beta-propargylation or 11-beta-allenylation. The role of the catalytic effect of copper chloride and of the solvent is evaluated. Confirmation of the structural assignments of these new 3,3-ethylenethioxy-10-beta-propargyl (or 11-beta-allenyl)-19-nor-17-alpha-pregna-4,9-diene-21,17-carbolactones is reported.
