摘要：
There is provided a novel and efficient stereoselective total synthesis of epipodophyllotoxin and related epipodophyllotoxin compounds of the general formula ##STR1## wherein R.sup.1 and R.sup.2 each are independently hydrogen or (lower)alkoxy, or R.sup.1 and R.sup.2, taken together, is methylenedioxy; R.sup.4 and R.sup.6 each are independently hydrogen or (lower)alkoxy; and R.sup.5 is hydrogen or a phenol-protecting group; or an acid addition salt thereof. The present invention also provides novel intermediates and processes for the preparation of said intermediates, which are then converted into known antineoplastic agents.
