Abstract
A highly effective enantioselective monobenzoylation of 1,3-diols has been developed for the synthesis of 1,1-disubstituted tetrahydro-β-carbolines. The chemistry has been successfully applied to the asymmetric total synthesis of (+)-alstrostine G, which also features a cascade Heck/hemiamination reaction enabling facile construction of the pivotal pentacyclic core.

Abstract
The first asymmetric total synthesis of the monoterpenoid indole alkaloid arboduridine has been accomplished. The tricyclic A/B/D ring system was constructed by an enantioselective Michael reaction followed by intramolecular nucleophilic addition. Intramolecular α-amination of a ketone forged the piperidine ring, while a Horner-Wadsworth-Emmons (HWE) reaction was used to form the pyrrolidine ring. A reduction cyclization cascade led to formation of the tetrahydrofuran ring.

Abstract
AbstractChiral α-tertiary amines, a motif present in α,α-disubstituted α-amino acids, in a wide range of natural products, and many drugs and drug candidates, are important targets in organic chemistry. Among the possible strategies, 1,2-addition to chiral N-sulfinylketimines is one of the best routes to form chiral α-tertiary amines with a high level of stereoselectivity. In this review, we focus first on the addition of organometallic reagents or other nucleophiles as enols or ylides to chiral N-sulfinylketimines. Then secondly we cover a selection of applications of these additions in the synthesis of valuable biologically active compounds.1 Introduction2 1,2-Addition Reaction Methodologies2.1 Organolithium Reagent Additions2.2 Grignard Additions2.3 Organozinc Reagent Additions2.4 Organoindium Reagent Additions2.5 Organoboron Reagent Additions2.6 Strecker Reactions2.7 Palladium-Catalyzed Reactions2.8 Enols, Enolates, and Other Deprotonated Reagent Additions2.9 Ylide Additions2.10 Heteroatom Nucleophiles2.11 Miscellaneous Reactions3 Applications to the Synthesis of Biologically Active Molecules4 Conclusions
