Regiospecific Oxidation of Methyl Groups in Dimethylanisoles
Hauser, Frank M.,Ellenberger, Suzanne R.
, p. 723 - 724 (1987)
Dimethylanisoles in which one of the methyl groups is meta and the other is ortho or para are regiospecifically oxidized in high yield to the corresponding ortho- and para-substituted aldehydes by copper(II) and peroxydisulfate.Subsequent oxidation of the

An efficient electrochemical method for benzylic C(sp3)-H bond oxidation has been developed. A variety of methylarenes, methylheteroarenes, and benzylic (hetero)methylenes could be converted into the desired aryl aldehydes and aryl ketones in moderate to excellent yields in an undivided cell, using O2 as the oxygen source and lutidinium perchlorate as an electrolyte. On the basis of cyclic voltammetry studies, 18O labeling experiments, and radical trapping experiments, a possible single-electron transfer mechanism has been proposed for the electrooxidation reaction.
Volatiles from the xylarialean fungus Hypoxylon invadens

, p. 734 - 746 (2018/04/16)
The volatiles emitted by agar plate cultures of the xylarialean fungus Hypoxylon invadens were investigated by use of a closed loop stripping apparatus in combination with GC-MS. Several aromatic compounds were found that could only be identified by comparison to all possible constitutional isomers with different ring substitution patterns. For the set of identified compounds a plausible biosynthetic scheme was suggested that gives further support for the assigned structures.

(Diacetoxyiodo)benzene in the presence of acetic–trifluoroacetic acid in THF has been developed for the chemoselective para-methoxybenzylic C–H bond oxidation to provide aryl carbonyl compounds at room temperature. The reaction condition is also applicable for the chemoselective deprotection of para-methoxybenzyl (PMB) ether in the presence of benzyl ether.
A 4-methoxy-2-methyl-benzyl cyanide synthesis method
-
, (2019/02/02)
The invention relates to a synthesis method for 4-methoxy-2-methyl benzyl cyanide. The synthesis method takes 3, 4-dimethylphenol which is cheap and simple and easy to purchase as the raw material, and comprises six steps: methylation, oxidation, Witting reaction, alkene ether hydrolysis, oximation and dehydration. The synthesis method uses the simple and cheap raw material, is simple to operate, is easy for industrial production, has short production cycle, only needs purification in the last step of the six so as to obtain high-quality 4-methoxy-2-methyl benzyl cyanide, and avoids using extremely toxic substances like NaCN and KCN, thus filling the blank home and abroad.

Although there are many estrogen receptor antagonists with improved tissue selectivity profiles compared with tamoxifen, optimal tissue selectivity has not yet been demonstrated. As such there is still a need for additional diversity and new chemical scaf
