The first enantioselective synthesis of (+)-isolysergol was completed in 12 steps from commercially available materials by a novel approach that features a late stage microwave-mediated, diastereomeric ring-closing metathesis catalyzed by a chiral molybdenum catalyst to simultaneously form the D ring and set the stereocenter at C(8).

Optically pure N-Boc-4-bromo-N-methyl-1-tosyl-D-tryptophan methyl ester (D-4), a key intermediate in the synthesis of optically active ergot alkaloids such as chanoclavine-I (7) and costaclavine (8), was prepared from N-acetyl-4-bromo-D-tryptophan (D-11) obtained from 4-bromoindole (9) and DL-serine (10) in two steps.
