Imino Diels-Alder adducts. I. Two furo[3,2-c]quinoline diastereoisomers.
The structures of two diastereoisomers of 9-chloro-8-fluoro-4-phenyl-2,3,3a,4,5,9b-hexahydrofuro[3,2-c]quinoline, C(17)H(15)ClFNO, are very similar. The orientation of the furan ring, as a result of its fusion to the quinoline nucleus, constitutes the significant difference between the two structures. The dihedral angles between the furan and phenyl rings are 73.4 (1) and 63.8 (1) degrees.
