17β-Acetoxy-3-methoxyestra-1,3,5(10)-triene-14,17α-dicarbaldehyde (1) undergoes base-mediated intramolecular condensation to give a mixture of the (141R)- and (141S)-141,20-hemiacetals of (20R)-14-formyl-20-hydroxy-3-methoxy-19-nor-17α-pregna-1,3,5(10)-triene-21,17-carbolactone (2).The synthesis of derived 19-nor-17-spirolactones is described, and it is shown that 14-functionality participates in unusual intramolecular rearrangements.
