  • Highly diastereoselective synthesis of 11β,17β-diaryl-18a-homo-19-nor steroids
    作者:Eckhard Ottow、Arwed Cleve、Günter Neef、Wolfgang Schwede
    DOI:10.1002/prac.19973390164
    日期:——
    In a highly diastereoselective fashion novel 11 beta, 17 beta-diaryl steroids 17 and 18 were synthesized via Birch-type reduction [1] of styrylic precursors 11 and 15. Both precursors were readily available by Suzuki-type coupling reactions [2] of aromatic boronic acids [3] and the corresponding enol triflates 6, 10, and 14. Regioselective 17-enol triflate formation in presence of a 11-keto function could be demonstrated in case of steroid 5. The remarkably high degree of stereoselectivity observed parallels results from the natural series [4] and demonstrated a broader applicability of such single electron transfer reductions in stereoselective transformations on the steroid skeleton.

  • A partial synthesis of 13-ethyl-11-methylene-18,19-dinor-17α-pregn-4-en-20-yn-17-ol (desogestrel) based upon intramolecular oxidation of an 11β-hydroxy-19-norsteroid to the 18 → 11β-lactone

    日期:——
    A partial synthesis of the 13-ethyl-18-norsteroid desogestrel is reported. The key step in this synthesis is the intramolecular oxidation of 11β-hydroxyestr-5-ene-3,17-dione cyclic bis-(1,2-ethanediyl acetal) 3 with Pb(OAc)4 and iodine to 3,3:17,17-bis[1,2-ethanediylbis(oxy)]-11β-hydroxyestr-5-en-18-oic acid γ-lactone 2.

    An improved synthesis of 13 beta-ethyl-11-methylenegon-4-en-3,17-dione with the total yield of 57% starting from 13 beta-ethyl-11 alpha-hydroxy-gon-4-ene-3,17-dione is described.
