Tin(IV) chloride and titanium(IV) chloride mediated cyclizations of the ortho-allyl-substituted homochiral hydroxyanthraquinone acetals (7)-(10), prepared by optimized reductive Claisen rearrangements, have afforded monochloro and dichloro tetracyclic products, the stereochemistry of which has been assigned by using n.m.r. techniques.An SN2-like process in which the dioxolan ring is maintained as an ion pair intermediate is favoured when either tin(IV) chloride or titanium(IV) chloride is used at -78 deg.Thereafter the direction of addition of chloride at C9 is largely governed by the orientation of this ion pair.An alternative path which probably involves a free oxocarbenium ion predominates at higher temperatures.An adjacent methoxy group on the anthraquinone lowers the stereoselectivity at both C7 and C9, possibly by bidentate coordination of the Lewis acid involving the quinone carbonyl, the methoxy oxygen and the acetal oxygens.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Related Products of 19132-06-0. In my other articles, you can also check out more blogs about Related Products of 19132-06-0
