Ethyl 6′-amino-5′-cyano-2′-methyl-2-oxospiro[indoline-3,4′-pyran]-3′-carboxylate
In the title compound, C(17)H(15)N(3)O(4), the atoms of the spiro pyran ring are nearly planar with a maximum deviation of 0.0188 (14) Å. The benzene and pyrrole rings make a dihedral angle of 5.71 (6)°. The indole system and the pyran ring are oriented at a dihedral angle of 82.94 (3)°. The crystal structure is stabilized by inter-molecular classical and non-classical N-H⋯O, N-H⋯N and C-H⋯O hy...
متن کاملPractical access to the proline analogs (S,S,S)- and (R,R,R)-2-methyloctahydroindole-2-carboxylic acids by HPLC enantioseparation.
An efficient methodology for the preparation of the α-tetrasubstituted proline analog (S,S,S)-2-methyloctahydroindole-2-carboxylic acid, (S,S,S)-(αMe)Oic, and its enantiomer, (R,R,R)-(αMe)Oic, has been developed. Starting from easily available substrates and through simple transformations, a racemic precursor has been synthesized in excellent yield and further subjected to HPLC resolution using...
متن کامل{(R,S Fc,S Fc)-2′′-Bromo-2-[1-(dimethylamino)ethyl-κN]-1,1′′-biferrocene}trihydridoboron
The title structure, [Fe(2)(C(5)H(5))(2)(C(14)H(19)BBrN)], contains a chiral and asymmetrically 2,2''-disubstituted biferrocene designed as precursor for enanti-oselective non-C(2)-symmetric biferrocenyldiphosphine catalysts. The mean bond lengths in the biferrocene unit are Fe-C = 2.048 (10) Å and C-C = 1.427 (8) Å within the cyclo-penta-dienyl rings. The B-N bond lengths of the BH(3) protecte...
متن کامل1-(Prop-2-ynyl)indoline-2,3-dione
The structure of the title compound, C11H7NO2, is isotypic to that of its homologue, 1-octylindoline-2,3-dione [Qachchachi et al. (2013 ▶). Acta Cryst. E69, o1801]. The indoline ring and the two carbonyl O atoms are approximately coplanar, the largest deviation from the mean plane being 0.021 (1) Å for one of the O atoms. The mean plane through the fused ring system is nearly perpendicular to t...
متن کاملAn efficient synthesis of a spirocyclic oxindole analogue.
An efficient, scaleable synthesis approach towards the spirocyclic oxindole analogue 1'-(tert-butoxycarbonyl)-2-oxospiro[indoline-3,4'-piperidine]-5-carboxylic acid (1) is described. The key steps are dianion alkylation and cyclization of ethyl 2- oxindoline-5-carboxylate (4) and demethylation of the resulting spirocyclic oxindole ethyl 1'-methyl-2-oxospiro[indoline-3,4'-piperidine]-5-carboxyla...
