Article abstract of DOI:10.1107/S0108270193014404

The crystal structure and the relative stereochemistry of the four asymmetric centers of an unusual C-4a hydroxylated decahydroquinolone, phenyl 1,2α,3,4,4aα,5β,6,7,8,8aα-decahydro-4a-hydroxy-4-oxo-2-propyl-5-vinylquinoline-1-carboxylate, C21H27NO4, are reported.The H and OH groups at the ring juncture are cis to each other as are the two H atoms α to the N atom.The vinyl and OH groups are also cis to each other.The N atom is sp² hybridized.
