A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 31608-22-7, Name is 2-(4-Bromobutoxy)tetrahydro-2H-pyran, molecular formula is C9H17BrO2. In a Article，once mentioned of 31608-22-7, Computed Properties of C9H17BrO2
ALKYLATION REACTIONS OF ANIONS DERIVED FROM 2-BENZENESULPHONYL TETRAHYDROPYRAN AND THEIR APPLICATION TO SPIROKETAL SYNTHESIS
Reaction of 3,4-dihydro-2H-pyran or 2-methoxytetrahydropyran with benzenesulphinic acid gave 2-benzenesulphonyl tetrahydropyran (1).Deprotonation of (1) followed by alkylation with carbonyl compounds or halides gave cyclic enol ether addition products by spontaneous elimination of benzenesulphinic acid.Interception of the initial addition products with aldehydes by reductive desulphonylation to give alkylated tetrahydropyran derivatives proceeded in moderate yield using sodium naphthalenide.Several of the cyclic enol ether addition products were further converted to spiroketals including syntheses of natural product pheromones from Dacus oleae and Paravespula vulgaris.
