Abstract

The synthesis of several N-6 derivatives of elymoclavine (3) and potential alkylating derivatives of 6-methyl-8-aminoergolines (12) is described. These compounds were screened for prolactin-inhibiting ability and 6-propyl-8-hydroxymethyl-8-ergolene (9) was found to be as active as the most potent Prolactin inhibitors reported to date. The total synthesis of racemic methyl dihydrolysergate I (23), having a trans C, D ring fusion, from the tricyclic ketone 18 is also described.
