SELECTIVE PHOTOCYCLIZATION REACTIONS OF (Z)-N-ACETYL-alpha-DEHYDRO(9-PHENANTHRYL)ALANINE ALKYL ESTERS AND N ‘,N ‘-DIALKYLAMIDES TO DIBENZO[f,h]ISOQUINOLINE DERIVATIVES

(Z)-N-Acetyl-alpha-dehydro(9-phenanthryl)alanine alkyl esters and N’,N’-dialkylamides [(Z)-1] were synthesized, and their photocyclization behavior in methanol was explored. The irradiation of (2)-1 in a protic polar solvent at wavelengths greater than 280 nm caused selective cyclization reactions, producing the corresponding dibenzo[f,h]isoquinoline derivatives. Moreover, the formation efficiency of these derivatives showed strong dependence on the steric bulk and electronic property of the alkoxycarbonyl and dialkylaminocarbonyl groups.

A Simple Highly Regioselective or Regiospecific Substitution Method of Aromatic Isoquinoline

A novel simple version for highly regioselective or regiospecific substitution method of aromatic isoquinoline has been developed by utilizing the reaction condition of Bischler-Napieralski cyclization. The proposed reaction mechanism was successfully indirect confirmed. In this method, chloroiminium intermedium A was formed from the amide compound with phosphoryl chloride, and intramolecular cyclized was preceded. The final structure of aromatic isoquinoline was obtained through removing the acidic hydrogen atom by sodium borohydride served as a base rather than reductive agent as expected.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 17557-76-5. SDS of cas: 17557-76-5.

IMPROVED METHOD FOR THE DETERMINATION OF THE OXYGEN ISOTOPIC COMPOSITION OF CELLULOSE

A modification of a chemical preparation procedure for oxygen isotope analysis of cellulose has been developed which yields greater precision and requires less time for sample preparation. In the place of isoquinoline, zinc is used to remove HCl from the reaction products of the sample and HgCl2. The two methods give systematically different results because isoquinoline biases measurements by contaminating the sample with additional CO2. For the zinc method, precision is +/-0.2 parts per thousand (1 sigma standard deviation) compared with +/-0.9 parts per thousand for the isoquinoline method.
