Asymmetric Hydroxylation

Over the last few decades, considerable research efforts have been directed toward the development of effective chemical syntheses of camptothecin and its analogs. The last comprehensive review of this area was published in 2003 and many effective new methods have since been reported for the stereoselective synthesis of the camptothecin alkaloids. In this account, we have summarized most of the novel synthetic approaches developed for the synthesis of camptothecins during the last decade. We have focused on strategies for the construction of the pentacyclic ring system and the different methods used to install the chiral quaternary center on the E ring of camptothecin.1 Introduction2 Synthesis of Racemic Camptothecins3 Enantioselective Synthesis of Camptothecins3.1 Sharpless Asymmetric Dihydroxylation3.2 Catalytic Asymmetric Cyanosilylation3.3 Auxiliary-Induced Asymmetric Carbonyl Addition3.4 Catalytic Asymmetric Ethylation3.5 Asymmetric Hydroxylation4 Conclusion

Herein presented is a review of the reactivity and synthetic utility of ortho-quinone methides and ortho-quinone methide imines. These versatile intermediates have received significant attention in the literature and new methods for their preparation and reaction as well as recent applications in total synthesis are discussed.1 Introduction2 Conjugate Addition Reactions3 Concerted Cycloaddition Reactions4 Stepwise Addition Reactions5 Applications in Total Synthesis6 Conclusion
