Aryne-Mediated Arylation of the 3-Benzazepine Scaffold: One-Pot Synthesis of 1-Aryl-3-methyl-2,3,4,5-tetrahydro-1H-3-benzazepines
摘要:
The coupling of beta-amino carbanions derived from 3-benzazepines with in situ generated arynes has been demonstrated as a convenient route for the direct synthesis of a variety of 1-aryl-3-methyl-2,3,4,5-tetrahydro-1H-3-benzazepines, including the biologically active drug molecule SCH 12679.

An efficient and simple procedure for the syntheses of 4-aryl-1,2,3,4-tetrahydroisoquinolines and 1-aryl-2,3,4,5-tetrahydro-3-benzoazepines has been developed. The approach uses easily available starting materials and requires just three steps. The hydroamination of an enol carbamate is the key step. This general and direct method has been applied to the total synthesis of the natural alkaloid cherylline

The present application discloses pyridinyl acrylamide derivatives of the formula (I) wherein X is opt.subst. pyrid-3-yl, pyrid-4-yl; A is -C(=O)-, -S(=O)2-, -C(=S)-, -P(=O)(R5)- (R5 is C1-6-alkyl, C1-6-alkoxy, hydroxy); B is a single bond, -O-; D is a single bond, -O-, -CR7R8-, -NR9-; m is 0-12, n is 0-12, m+n is 1-20. The compounds are useful for the inhibiting of the enzyme nicotinamide phosphoribosyltransferase (NAMPRT), and to medical use of such pyridinyl acrylamide derivatives.

Chemical behavior of 1,6,7-trisubstituted 2-methyl-1,2,3,4-tetrahydroisoquinolinium 2-methylides 4 was investigated in fluoride-ion induced desilylation reaction of 1,6,7-trisubstituted 2-methyl-2-(trimethylsilyl)-methyl-1,2,3,4-tetrahydroisoquinolinium iodides 3. The 1-nonsubstituted (4a,b) and 1-alkyl-substituted ylides (4c,d) gave mixtures of five products (7-11), but the 1-phenyl-substituted analogues (4e,f) yielded (E)- and (Z)-2,3-disubstituted 5-benzylidene-1,3-cyclohexadiene-6-spiro-3'-1'-methylpyrrolidines (E)-5 and (Z)-5 and 7,8-disubstituted 3-methyl-1-phenyl-2,3,4,5-tetrahydro-1H-3-benzazepines 6. The mechanisms of the rearrangement are discussed.
