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.
