In the title compound, C(24)H(25)NO, the phenyl and diphenyl-methanol substituents are syn to each other. The pyrrolidine ring has an envelope conformation with the flap atom being the C atom bearing the phenyl substituent. The hy-droxy group forms an intra-molecular hydrogen bond with the pyrrolidine N atom, and the phenyl rings lie to same side of the mol-ecule. The crystal packing features C...

In the title compound, C26H22N2O4, the central pyrrolidine ring adopts a twist conformation and the cyclo-pentane ring of the dihydro-acenapthylene group adopts an envelope conformation with the spiro C atom as the flap. The naphthalene ring system of the dihydro-acenaphthyl-ene group forms dihedral angles of 83.4 (9) and 61.3 (7)°, respectively, with the mean planes of the pyrrolidine and indo...

An enantioselective total synthesis of ( R )-bgugaine and the first )-irnidine are reported. The key steps asymmetric ‘clip-cycle’ formation pyrrolidine ring in 94:6 e.r., which is common to both natural products, followed by Liebeskind–Srogl coupling Wolf-Kishner reduction. route yields 6 overall 33% 18% respectively.

The mol-ecule of the title compound, C(23)H(23)ClN(2)O(4), contains a quinolyl unit linked to a functionalized pyrrolidine system with a 3,4-trans arrangement of the substituents. The unit cell contains two stereoisomers that have the absolute stereochemistry 3S,4R and 3R,4S. The pyrrolidine ring adopts a twist conformation with pseudo-rotation parameters P = 258.2 (3)° and τ(M) = 35.3 (1)°. Th...

In the title compound, C30H27ClN4O, the central pyrrolidine ring adopts an envelope conformation with the methyl-ene C atom being the flap. The quinoxaline and indane rings are each essentially planar, with r.m.s. deviations of 0.027 (1) and 0.0417 (1) Å, respectively. The pyrrolidine ring forms dihedral angles of 88.25 (1) and 83.76 (1)° with the quinoxaline and indane rings, respectively. A w...
