Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 323196-43-6, is researched, Molecular C13H19ClN2O, about Medium-Ring Effects on the Endo/Exo Selectivity of the Organocatalytic Intramolecular Diels-Alder Reaction, the main research direction is ether fused cyclohexenecarboxaldehyde diastereoselective preparation; diastereoselectivity intramol Diels Alder reaction medium ring bridged trienal; imidazolidinone catalyst diastereoselectivity intramol Diels Alder reaction; transition state structure calculation intramol Diels Alder reaction; dependence diastereoselectivity intramol Diels Alder reaction size bridging ring; bromoperhydroisobenzofurancarboxylic acid oxatricyclotridecadienecarboxaldehyde nitrophenylhydrazone mol crystal structure; oxatricyclotetradecadienemethanol dinitrobenzoate mol crystal structure.HPLC of Formula: 323196-43-6.
Previous work showed that the butadienyloxoninylpropenal I (R = PhSiMe2) underwent diastereoselective intramol. Diels-Alder reactions in the presence of II•HCl or ent-II•HCl to yield either the endo cycloadduct III as the major cycloadduct in 15:1 dr (using ent-II) or the exo cycloadduct IV (suitable for elaboration to the eunicellins) as the sole diastereomer (using II). The diastereoselectivities of the intramol. Diels-Alder reactions of medium ring cyclic ether-containing trienecarboxaldehydes in the presence of II•HCl or ent-II•HCl and the calculated structures and enthalpies and free energies for diastereomeric transition state structures for the cycloadditions were determined The structures of a dibromoperhydroisobenzofurancarboxylic acid, an oxatricyclotridecadienecarboxaldehyde hydrazone, and an oxatricyclotetradecadienemethanol dinitrobenzoate were determined by X-ray crystallog.
