摘要

The first synthesis of the trans-dihydro diol and syn-diol epoxide derivatives of a biologically active cyclopenta [a] phenanthrene is described. The cyclopenta [a] phenanthrene skeleton is rapidly and efficiently assembled utilizing the Lewis acid-catalyzed Diels-Alder reaction of 1, 2-dihydr0-7-methoxy-4-vinylnaphthalene (5) with an a-heterosubatituted cyclopentenone, a'cyclopentynone" equivalent. It was found that the Dieh-Alder reaction of a-( ...
