The synthesis and biological activities of a series of (+/-)-hexahydro-7H-indolo[3,4-gh][1,4]benzoxazine derivatives [(+/-)-trans-9-oxaergolines] with central dopamine (DA) agonist properties are described. The compounds were prepared from [2aRS-(2a alpha,4 beta,5 alpha)]-4-amino-1,2,2a,3,4, 5-hexahydro-1-(phenylmethyl)benz[cd]indol-5-ol (6b) by alkaline cyclization of the corresponding N-chloracetamide
