The (R,R)-enantiomers of trans-indeno[1,2-b]-1,4-oxazines demonstrate dopaminergic activity, whereas the (S,S)-enantiomers demonstrate .alpha.-adrenergic antagonist activity. They are prepared by cyclization of the appropriate chiral 2-amino-1-hydroxyindane.
(R,R)-顺式异构体的trans-茚并[1,2-b]-1,4-噁嗪表现出多巴胺活性,而(S,S)-顺式异构体表现出α-肾上腺素受体拮抗活性。它们是通过将适当的手性2-氨基-1-羟基茚烷环化制备而成。
