The first total synthesis of alangicine (3), an Alangium lamarckii alkaloid, has been achieved in the form of a racemic modification by means of an initial alkaline hydrolysis of the (+/-)-tricyclic ester 6 and succeeding steps proceeding through the intermediates (+/-)-7, (+/-)-10, and (+/-)-9.A parallel synthetic route starting with the (-)-tricyclic ester 6, derived from (+)-cincholoipon ethyl ester (8), produced the chiral target molecule (+)-3 via the intermediates (-)-7, (-)-10, and 9.The identity of the synthetic (+)-3 with alangicine unequivocally established the structure and absolute stereochemistry of this alkaloid.The (13)C nuclear magnetic resonance spectra of (+/-)-alangicine (3) and the ipecac and Alangium alkaloid psychotrine (18) confirmed their endocyclic double bond structures in the dihydroisoquinoline moiety.Catalytic reductions of 11, (+/-)-12, and 15 using hydrogen and Pd-C were investigated, and the results have shown that hydrogenolysis of the benzyloxy group proceeds much faster than saturation of the endocyclic C=N bond.Keywords – alangicine; psychotrine; structure; absolute configuration; stereoselective synthesis; (13)C NMR; CD; benzyl ether; hydrogenolysis

First representatives of a new family of isoquinolines, so called boroisoquinolines, were synthesized and characterized. The synthesis was based on the insertion of the difluoroboranyl group into the 1-methylidene-3,4-dihydroisoquinoline core. The optimization of the 2-difluoroboranyl-3,4-dihydroisoquinoline-1(2H)-ylidene core led to efficient fluorescence in a range of 400-600 nm with outstanding (>100 nm) Stokes shifts. The compounds might be suitable for reversible or irreversible labelling of proteins, particularly the cannabinoid receptor CB2.

Treatment of the trifluoroacetyl enamides of dihydroisoquinolines 2 with diverse Grignard reagents afforded tertiary trifluoromethyl-carbinols 4 by facilitating the addition of tertiary carbinols to the beta-carbon of enamides 2. Based on the confirmed formation of vinylogous amides 3, the transformation likely proceeds via unique acyl group rearrangement to the beta-carbon of the enamide and subsequent nucleophilic addition of the Grignard reagent. Given the synthetic utility and novelty of this reaction, this work may open new avenues for the synthesis of pharmaceutically important tertiary trifluoromethylcarbinols on cyclic enamide systems.
