Propargylic alcohols are readily available bifunctional (alkyne and hydroxyl groups)
synthons, which recognize as one of the attractive synthetic feedstock in organic …

Over the past decades, the development of enantioselective catalysis using organocatalysts
has evolved into an active research field and a number of enantioselective transformations …

An enantioselective reduction of simple carbenium ions with cyclohexadienes containing a
hydridic C− H bond at an asymmetrically substituted carbon atom is disclosed. The net …

The development of transition metal‐catalyzed enantioselective propargylic substitution
reactions has gained much progress in recent years, however, no successful example with …

Dehydration is an abundant and promising process in chemical, biochemical, and industrial
fields. Dehydration methods can contribute to building a modern and sustainable society …

A highly efficient kinetic resolution (KR) of racemic tertiary allylic alcohols was achieved
through an intramolecular allylic substitution reaction using a co-catalyst system composed …

Asymmetric Brønsted acid catalysis has been recognized as a powerful concept for
asymmetric synthesis. In the process of pursuing more robust and highly effective chiral …

This review discusses the progress achieved in chiral phosphoric acid (CPA)-catalyzed
organic reactions. CPA has demonstrated great versatility as a catalyst, effectively …

Carbenium ions had been suspected and subsequently shown to be key intermediates of a
large family of cationic transformations. An enormous body of work is dedicated to their …

We recently proposed a transition-state model for asymmetric propargylic substitution
reactions of propargylic alcohols catalyzed by optically active thiolate-bridged diruthenium …
