Fustero, Santos; Jimenez, Diego; Moscardo, Javier; Catalan, Silvia; del Pozo, Carlos published their research in Organic Letters on December 6 ,2007. The article was titled ãEnantioselective Organocatalytic Intramolecular Aza-Michael Reaction: a Concise Synthesis of (+)-Sedamine, (+)-Allosedamine, and (+)-Coniineã?HPLC of Formula: 813433-76-0 The article contains the following contents:
The intramol. aza-Michael reaction of carbamates bearing remote α,β-unsaturated aldehydes under organocatalytic conditions took place with good yields and excellent ee’s when Jorgensen catalyst was used in the process, giving rise to the enantioselective formation of several five- and six-membered heterocycles. The developed methodol. was applied to the synthesis of three piperidine alkaloids I, II and III. The results came from multiple reactions, including the reaction of (S)-tert-Butyl 3-(2-hydroxyethyl)morpholine-4-carboxylate(cas: 813433-76-0HPLC of Formula: 813433-76-0)
(S)-tert-Butyl 3-(2-hydroxyethyl)morpholine-4-carboxylate(cas: 813433-76-0) belongs to esters. They are important in biology, being one of the main classes of lipids and comprising the bulk of animal fats and vegetable oils.Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones.HPLC of Formula: 813433-76-0
