Syn-addition in organic chemistry happens when certain factors do not allow one of the reactants to rotate as an intermediate. Before the reaction starts, the site where the addition occurs is locked in place due to its pi-bond holding the structure in place. The first step of an addition...
What is the difference between a chemical change and a chemical reaction? Explain the advantages of using Pyridium tribromide over liquid bromine in an addition reaction for the bromination of stilbene. Explain the difference between (E)-stilbene and (Z)-s...

An N3-(p-methoxyphenoxy)acetyloxazolidine-2-thione has been synthesized and employed in glycolate asymmetric aldol addition reactions with aromatic and aliphatic aldehydes. It was determined that the titanium tetrachloride medicated aldol reaction afforded diastereoselectivities that ranged from 75:25 to 94...

Reagent control in the aldol addition reaction of chiral boron enolates with chiral aldehydes. Total synthesis of (3S,4S)-Statine Boron enolates bearing menthone-derived chiral ligands are capable of fair to excellent diastereocontrol in their reactions with chiral aldehydes. Thioeste...

Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) has been reported in patients taking NSAIDs such as NAPROSYN Tablets, EC-NAPROSYN, and ANAPROX DS. Some of these events have been fatal or life-threatening. DRESS typically, although not exclusively, presents with fever, rash, lymphad...
The reaction can tolerate aryl and aliphatic groups at the α-position of VCPs, while VCP substrates with vinyl or alkynyl substitutions are not suitable ones. In addition, this reaction can also be used to synthesize bicyclic rings if an aryl group is attached to the vinyl......
