Carbon-Carbon Bonds Formed by Lewis Acid Catalysis or Photoactivation
… quaternary centers from propargylic alcohols, organoboronates, and Lewis acids. Lewis acids can also be used to facilitate a mild Friedel-Crafts reaction between electron-rich aromatics and allylic or benzylic alcohols. Moreover, these methods can be applied to the synthesis of natural …

Cascade Transformations in Organic Synthesis: I. The Interception of Carbene Alkyne Metathesis Intermediates II. Photo-Activation of Hydrazones III. Organocatalyzed Cascade Conjugate Addition/Aldol Annulation of Organoboronates
… tandem conjugate addition/Aldol annulation of organoboronates was discussed in the last chapter. A variety of nucleophiles showed good compatibility with heterocycles. In addition, the strength of boron enolate intermediates were examined by intercepting with various electrophiles.

New methodologies and approaches to reaction discovery in transition metal catalysis
… Suzuki-Miyaura coupling of potentially unstable organoboronates was developed. Biaryls in which one or more of the aryl rings are heteroarenes or fluorinated arenes are found widely in medicinal chemistry and materials science, but are challenging to prepare by Suzuki-Miyaura coupling because of …
