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...
A tandem syn-selective conjugate addition - Nef reaction was observed when phenylnitromethane and oxygenated derivatives were allowed to react with an enoate derived from D-mannitol at rt in the presence of TBAF or DBU. While nitro-adducts predominate after 4h of reaction, the corresponding ketones...
The Aldol addition is the reaction between enolizable carbonyl compounds with aldehydes or ketones yielding β-hydroxy carbonyl compounds. It is named after the products of the reaction when two aldehydes are reacted (aldehyde-alchohol). The reaction was independently discovered by Alexander Borodin in...
