Introduction to the Electromagnetic Spectrum and Spectroscopy
Synthesis of Boron Enolates for Aldol Condensation
Boron Enolates for Aldol Synthesis and Other Reactions
How the E-enolate selectively produce anti-product in order to obtain directed aldol synthesis.
Directed Aldol Synthesis: Part 2 – Syn and Anti control using Zimmerman Traxler principle
Formation of a cyclic transition state during enolate formation which controls formation of E-enol or Z-enol
Directed Aldol Synthesis: Part 1 – Formation of E-Enolate and Z-Enolate
Aldol condensation - leading to aldol or ketol which can undergo dehydration to produce the alpha,beta-unsaturated aldehyde or ketone
Aldol Condensation – Acid Catalyzed
Base catalyzed dehydration of aldol or ketol leading to alpha,beta-unsaturated carbonyl compound.
