Experiments Directed Towards the Synthesis of Anthracyclinones. XX. Titanium(IV)- and Tin(IV)-Mediated Cyclizations of ortho-Allyl-Substituted Homochiral Dioxans

Titanium(IV) chloride mediated cyclization of the ortho-methoxylated 1,3-dioxan (5) gives a high yield of a mixture (10:1) of the (7R)-tetracycles (18) and (19) which are epimeric at C 9.The exclusive formation of the (7R) stereochemistry results from Ss
