An unexpected yet disciplined course of catalytic Mukaiyama-aldol reaction instead of the expected vinylogous Mukaiyama-aldol reaction has been observed for the reaction of silyloxyfuran with various aldehydes under Lewis acid catalytic control in water-containing solvents.

Mukaiyama aldol reactions in aqueous media have been surveyed. While the original Mukaiyama aldol reactions entailed stoichiometric use of Lewis acids in organic solvents under strictly anhydrous conditions, Mukaiyama aldol reactions in aqueous media are not only suitable for green sustainable chemistry but are found to produce singular phenomena. These findings led to the discovery of a series...

The development of efficient methods for the asymmetric Mukaiyama aldol reaction in aqueous solution has received great attention. We have developed a new series of chiral lanthanide-containing complexes that produce Mukaiyama aldol products with outstanding enantioselectivities. In this paper, we describe an optimized ligand synthesis, trends in stereoselectivity that result from changing lant...

A directed cross-aldol reaction of silyl enol ethers with carbonyl compounds, such as aldehydes and ketones, promoted by a Lewis acid, a reaction which is now widely known as the Mukaiyama aldol reaction. It was first reported in 1973, and this year marks the 40th anniversary. The directed cross-aldol reactions mediated by boron enolates and tin(II) enolates also emerged from the Mukaiyama labo...

Herein, we describe the first asymmetric total synthesis of (-)-martinelline ((-)-2) and the second total synthesis of (-)-martinellic acid ((-)-1) by employing a tandem Mukaiyama-Mannich reaction/aminal cyclization as the key step.

Amides with quaternary stereogenic centers have been synthesised by catalytic asymmetric vinylogous Mukaiyama aldol reactions. The chiral copper-sulfoximine catalyst gives rise to products with moderate to good yields and up to 92% ee.
