Abstract

Key indicatorsSingle-crystal X-ray study T = 293 K Mean '(C±C) = 0.003 A Ê R factor = 0.045 wR factor = 0.135 Data-to-parameter ratio = 14.3For details of how these key indicators were automatically derived from the article, see

2,4,4a,5,6,7,9,9a-Octahydrofuro[2,3-f]indolizin-7-one

“…The fused furan ring is almost planar (mean deviation = 0.037 A Ê ). Bond lengths and angles in the indolizine ring system are in agreement with values from the literature (Camus et al, 2000(Camus et al, , 2003Lokaj et al, 1999). Atom N10 is sp 2 hybridized, as evidenced by the sum of the valence angles around it (359.3 ).…”

“…2) and help to stabilize the crystal structure of the compound. Bond lengths and angles in the indolizine ring system are in good agreement with values from the literature (Camus et al, 2003;Lokaj et al, 1999).…”

(10aS)-6-Methoxy-1,10a-dihydropyrrolo[1,2-b]isoquinoline-3,10(2H,5H)-dione

“…This may be due to the fact that atoms O2 and O3 participate in intermolecular van der Waals forces. Bond lengths and angles in the indolizine ring system are in good agreement with values from the literature (Camus et al, 2000(Camus et al, , 2003Lokaj et al, 1999).…”
