چکیده
In the title compound, C(34)H(32)N(2)O(7), the methyl group and methylene H atoms of the ethoxycarbonyl substituent are disordered over two positions with site occupancy factors for the major and minor conformers of 0.594 (8) and 0.406 (8), respectively. The unsubstituted ring of the pyrrolizine ring system exhibits a twist conformation, the other an envelope conformation. In the crystal structure, mol-ecules are linked through C-H⋯O hydrogen bonds; intramolecular C-H⋯O interactions are also observed.

In the title compound, C(24)H(21)ClN(4)O(2)S, the two adjacent spiro junctions link an almost planar (r.m.s. deviation = 0.017 Å) 2-oxindole ring, a hexa-hydro-1H-pyrrolizine ring and a tetra-hydro-imidazo[2,1-b]thia-zole ring. In the crystal, inversion dimers linked by pairs of N-H⋯N hydrogen bonds occur, generating an R(2) (2)(16) loop.

The interaction of 2-ethoxymethylidene-3-oxo esters and their analogues with 5-aminotetrazole is an efficient synthetic approach to novel azaheterocycles. 2-Ethoxymethylidene-3-oxo esters bearing alkyl substituents react with 5-aminotetrazole to form ethyl 2-azido-4-alkylpyrimidine-5-carboxylates which are capable of subsequent nucleophilic substitution. The use of diethyl 2-ethoxymethylidenema...

In the title compound C38H32N4O3, one pyrrolidine ring adopts an envelope conformation with the N atom as the flap while other pyrrolidine ring adopts an twisted conformation. The pyrrolizine ring forms dihedral angles of 79.24 (5) and 77.57 (5)° with the chromene and indole rings, respectively. The carbonyl O atoms deviate from the least-square planes through the chromene and indole rings by 0...
