A facile synthesis of dibenzopyrroloazepinones via an electrophilic cyclisation of a biphenyl-acyliminium ion is described; an unusual 1,2-phenyl shift occurs when the C-1′ carbon is the more nucleophilic than the C-2′ carbon.

4-(2-Amino-propanamideyl)-3,4,5,6,7,8,9,10-octahydro-5,6, 8-trihydroxy-3-methyl-isocoumarin, which was isolated from Flaveria bidentis (L) Kuntze, had herbicidal activity and its structure was modified in this research in order to get the isocoumarin comp
Heck-mediated synthesis and photochemically induced cyclization of [2-(2-styrylphenyl)ethyl]carbamic acid ethyl esters and 2-styryl-benzoic acid methyl esters: Total synthesis of naphtho[2,1f]isoquinolines (2-azachrysenes)

We describe two new closely related total syntheses of naphtho[2,1-f]isoquinolines. The first synthesis consists of a Heck coupling reaction between trifluoromethanesulfonic acid 2-(2-ethoxycarbonylaminoethyl)phenyl esters and styrenes to give [2-(2-styrylphenyl)ethyl]carbamic acid ethyl esters. These compounds cyclize to give (2-phenanthren-1-yl-ethyl)carbamic acid ethyl esters, from which 2-azachrysenes can be obtained in a three-step sequence. The second synthesis includes a new total synthesis of 2-styrylbenzoic acid methyl esters by Heck coupling of methyl o-iodobenzoates to styrenes, followed by the transformation of the resulting benzoic acid derivatives into phenanthrene-1-carboxylic acid methyl esters and then into the target compounds by a six-step sequence including a Bischler-Napieralski cyclization.
