Cerium(III) chloride remarkably increases the rates of formation and yields of ketones in the reaction of lithium carboxylates with organolithiums
Y. Ahn,Theodore Cohen +1 more
TL;DR: The presence of CeCl 3 greatly increases the yield of ketones in the reaction of organolithiums with lithium carboxylates as discussed by the authors, which is a competing reaction except in special cases.

Enantiospecific synthesis of the (9S,18R)-diastereomer of the leukocyte adhesion inhibitor cyclamenol A.
Marc Nazaré,Herbert Waldmann +1 more
TL;DR: The first enantioselective total synthesis of the (9S, 18R)-diastereomer of this macrocyclic polyene lactam is reported on, which was necessary to first deprotect the intermediate formed after macrocycle formation and to generate the sensitive heptaene system in the last step by means of a Corey-Hopkins sequence.

Aziridine-Allylsilane-Mediated Total Synthesis of (-)-Yohimbane.
TL;DR: A total asymmetric synthesis of (-)-yohimbane and ent-alloyohimbanes is reported, which utilizes a novel aziridine-allylsilane cyclization reaction as a key step in the synthesis.

The McMurry Coupling and Related Reactions
Takeshi Takeda,Akira Tsubouchi +1 more
TL;DR: McMurry coupling has been recognized as one of the most efficient methods for the synthesis of alkenes from carbonyl compounds as discussed by the authors, which can be applied to the preparation of various alkenets that are otherwise difficult to prepare.
