Conformational Analysis. 50. C-Methyl-1,2,3,4-tetrahydroisoquinolines

Conformational equilibria in 1-, 3-, and 4-methyl-1,2,3,4-tetrahydroisoquinolines (THIQs) and the diastereomeric pairs of their 1,3- and 1,4-dimethyl homologs have been determined by measurement of H3/H4(trans) coupling constants and have been confirmed by molecular mechanics [MMP2(85)] calculations. The experimental -DeltaG values (a ? e) for the monomethyl compounds (computed values in parentheses) in kcal mol-1 are Me-1, 0.56 (0.46); Me-3, 1.63 (1.53); and Me-4, -0.32 (-0.22). Agreement of experimental and calculated values is very good as is the additivity of values for the dimethyl compounds (Table 1). Values for the corresponding hydrochlorides are Me-1, 0.19 (-0.34); Me-3, 1.15 (1.46); and Me-4, 0.35 (0.10) kcal mol-1. The less than satisfactory agreement of experimental with computed data here is probably due to neglect of solvation. The very small or negative DeltaG values for Me-1 and Me-4 were ascribed not only to the pseudoaxial (rather than axial) nature of Me(ax) and the absence of a syn-axial hydrogen on the side of the benzene ring but also to a peri interaction with H(8) and H(5), respectively, destabilizing equatorial methyl at positions 1 and 4. This was confirmed by comparing computed conformational energy values with values at corresponding positions in Delta3,4-tetrahydropyridines (THPs). While DeltaG in the two series is the same for Me-3 (THIQ numbering), that for Me-1 and Me-4 is considerably smaller in the THIQ than in the THP series which latter is devoid of peri hydrogens.

Direct reductive amination of ketones: Structure and activity of S-selective imine reductases from streptomyces

The importance and structural diversity of chiral amines is well-demonstrated by the myriad nonenzymatic methods for their chemical production. In nature, the production of amines is performed by transamination rather than by reduction of an imine precursor derived from the corresponding ketone. Imine reductases, however, show great potential in the reduction of cyclic imines that are stable towards hydrolysis in aqueous reaction media. Here, we report the catalytic activity of two S-selective imine reductases towards 3,4-dihydroisoquinolines and 3,4-dihydro-beta-carbolines and their activity in the direct reductive amination of ketone substrates. The crystal structures of the enzyme from Streptomyces sp. GF3546 in complex with the cofactor NADPH and from Streptomyces aurantiacus in native form have been solved and refined to a resolution of 1.9 A.

Formal [4 + 2] cycloaddition of imines with alkoxyisocoumarins

A new preparation of delta-lactams is reported. In the presence of a Lewis acid promoter, alkoxyisocoumarins engage a range of N-aryl and N-alkyl imines to form delta-lactams with a pendent carboalkoxy substituent. A sulfonamide-thiourea catalyst enables the synthesis of these products in moderate to good enantioselectivities.

1,4-Dehydrochlorination of 1-(1-haloalkyl)-3,4-dihydroisoquinolines as a convenient route to functionalized isoquinolines

1-Chloroalkyl-, 1-(2,2-dichloroalkyl)-, and 1-(trichloromethyl)-3,4-dihydroisoquinolines are synthesized by chlorination of 1-alkyl-3,4-dihydroisoquinolines with N-chlorosuccinimide. These novel chlorinated 3,4-dihydroisoquinolines are suitable precursors for functionalized isoquinolines by aromatization involving sequential 1,4-dehydrochlorination, tautomerization, and nucleophilic substitution.

Additive-free pd-catalyzed alpha-allylation of imine-containing heterocycles

An additive-free Pd-catalyzed alpha-allylation of different imino-group-ontaining heterocycles is reported. The activation of alpha-CH pronucleophiles (pKa (DMSO) > 25) occurs without the addition of strong bases or Lewis acids using only the Pd/Xantphos catalyst system. The reaction scope has been studied for various 5- and 6-membered nitrogen-containing heterocycles (yields up to 96%). Mechanistic investigations suggest an initial allylation of the imine-N followed by a Pd-catalyzed formal aza-Claisen rearrangement.

Synthesis and characterization of a diaziridinium ion. Conversion of 3,4-dihydroisoquinolines to 4,5-dihydro-3H-benzo[2,3]diazepines via a formal N-insertion process

A diaziridinium ion has been synthesized in high yield and its structure unambiguously confirmed by X-ray crystal analysis. The predicted N-transfer reactivity with olefins of this species was not observed. Instead, upon heating, the diaziridinium ion underwent ring opening to produce a dihydrobenzodiazepene product in good yield, thus achieving a formal N-insertion of the starting dihydroisoquinoline substrate. This process has been demonstrated on 11 total substrates.
