OXIDATION OF ARYL ALKYL KETONES TO ALPHA-ACYLOXY, ALPHA-(CAMPHORSULFONYLOXY), OR ALPHA-HYDROXY DERIVATIVES USING MANGANESE(III) ACETATE IN COMBINATION WITH CARBOXYLIC-ACIDS OR (1S)-(+)-10-CAMPHORSULFONIC ACID DEMIR, AS; CAMKERTEN, N; AKGUN, H; Tanyeli, Cihangir; MAHASNEH, AS; WATT, DS (Informa UK Limited, 1990-01-01) The α-oxidation of aryl alkyl ketones using manganese(III) acetate in the presence of various carboxylic acids and (1S)-(+)-10-camphorsulfonic acid provided a convenient synthesis of α-acyloxy, α-(10-camphorsulfonyloxy), and α-hydroxy derivatives in good yield.
Oxidation of Primary Alcohols to Aldehydes with N-Halamine-Containing Polymers Akdağ, Akın; Öztürk, Perihan (Georg Thieme Verlag KG, 2013-11-12) Polymeric N-halamines have been previously employed for organic reactions such as sulfide oxidation. In the present study, we employed polymeric N-halamines to oxidize primary alcohols selectively to the corresponding aldehydes in excellent yields. After reaction, the polymers can be recycled and then reused for the next reaction process.

Synthesis of Pyrazoles via Cul-Mediated Electrophilic Cyclizations of alpha,beta-Alkynic Hydrazones Zora, Metin (2011-11-18) Synthesis of pyrazoles via electrophilic cyclization of alpha,beta-alkynic hydrazones by copper(I) iodide is described. When treated with copper(I) iodide in the presence of triethylamine in refluxing acetonitrile, alpha,beta-alkynic hydrazones, prepared readily from hydrazines and propargyl aldehydes and ketones, undergo electrophilic cyclization to afford pyrazole derivatives in good to excellent yields. The reaction appears to be general for a variety of alpha,beta-alkynic hydrazones and tolerates the pr...
Synthesis of Indolizines by Dimerization of N-Propargylated Pyrroles via Allene Intermediates Kuzu, Burak; Gul, Sergen; Tan Uygun, Meltem; Mengeş, Nurettin; Balcı, Metin (2021-03-01) Ten different N-propargyl pyrrole derivatives having various substituents at the C-2 position were synthesized. These derivatives were converted into indolizine derivatives by the [2+2] cycloaddition reaction of pyrrole N-allene, forming in situ, by heating in PrOH in basic medium. The structures were characterized by NMR and X-ray crystallography. The N-propargylated derivatives smoothly underwent intermolecular cyclizations to produce indolizine derivatives in good yields. We proposed a radical mechanism ...
