Alkylierungsmittel vom Typ der a-Brom-a-ethoxyessigsaurederivate [l] erwiesen sich in vorangegangenen Untersuchungen als geeignete Synthone zur reversiblen Blockierung von Carboxylgruppen iiber enzymatisch spaltbare Alkoxycarbonyl-ethoxymethylester [a] sowie zur Herstellung entsprechender bioabbauba
The title compound, C 23 H 25 BrO 3 , was synthesized by the reaction of p-bromobenzaldehyde with dimedone and HClO 4 / SiO 2 in EtOH. In the molecule, the dihydropyran ring adopts a boat conformation and the two cyclohexene rings are in a trans conformation.
The asymmetric unit of the title compound, C~22~H~29~N~3~O~5~S, contains two independent molecules, __A__ and __B__, which differ slightly in the orientation of the ethyl and tosyl groups with respect to the attached pyrrolidine ring, as evidenced by the relevant torsion angles. In both molecules, t
