Wuensch, Bernhard; Nerding, Sven published the artcile< A facile and regioselective synthesis of donor-substituted 2-(2-halophenyl)acetaldehyde acetals>, HPLC of Formula: 112-63-0, the main research area is regioselective preparation donor substituted halophenylacetaldehyde acetal.
Starting from vanillin a facile and high yielding procedure for the preparation of the donor substituted (2-bromophenyl)- and (2-iodophenyl)-acetaldehyde acetals I [R = Br (II), I (III)] is described. Homologation of O-benzylvanillin to obtain the phenylacetaldehyde acetal I [R = H(IV)]succeeds by Wittig reaction with the Ph3P+CH2OMe Cl- and subsequent addition of methanol. IV is brominated with pyridinium bromide perbromide in methanol to yield the bromo acetal II in 65% yield from vanillin. Iodination of IV with iodine and iodic acid leads to the iodo acetal III.
Archiv der Pharmazie (Weinheim, Germany) published new progress about Acetals Role: SPN (Synthetic Preparation), PREP (Preparation). 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, HPLC of Formula: 112-63-0.
