In our constant search for new successors of agomelatine, we report herein a new series of compounds resulting from bioisosteric modulation of the naphthalene ring. The isoquinoline and tetrahydroisoquinoline derivatives were synthesized and pharmacologic
Isoquinoline synthesis by C-H activation/annulation using vinyl acetate as an acetylene equivalent

Vinyl acetate is used as an acetylene equivalent in rhodium(III)-catalysed C-H activation/annulation with aryl ketoxime esters. Extension to an aldoxime ester allows for a concise formal synthesis of decumbenine B.

7-Methoxy-3-methylsulfonyl-3H-benz[d]azepine (5) and 2-deuterio-3-(methyl-d3)-sulfonyl-3H-benz[d]azepine (14) were obtained from the reaction of the corresponding isoquinoline 2-oxides with methylsulfinylmethyl carbanion. A revised reaction mechanism is proposed on the basis of the results obtained by use of deuterated dimethyl sulfoxide-d6.

A ONE-POT ISOQUINOLINE SYNTHESIS BY CYCLODEHYDROGENATION OF BENZYLAMINOACETALS WITH CHLOROSULFONIC ACID
Kido, Kazuko,Watanabe, Yasuo
, p. 1151 - 1154 (2007/10/02)
A direct preparation of the fully aromatized isoquinolines (3a-l) by the cyclodehydrogenation of benzylamnoacetals (2a-l) with chlorosulfonic acid is described.Comparing the behavior of chlorosulfonic acid with that of sulfuric acid toward 1,2-dihydroisoquinoline, it is able to be suggested that benzylaminoacetals were cyclized first to 1,2-dihydroisoquinolines, subsequently, dehydrogenated to the fully aromatized isoquinolines by the hydride abstraction with ClSO3H.Subtitution by a larger R3 group than isopropyl in the acetal ArCH(R3)NHCH2CH(OEt)2, interfered this second step, so the corresponding isoquinolines could not be obtained.
