A compound of the formula III can then be cyclized to a 19-nor-androst-4-en-3-one by treatment with an acid or base, for example by refluxing in the presence of a strong acid capable of phase separation, such as p-toluenesulfonic acid Azeotropic distillation of the water of reaction. For example, 10- (3-0xobutyl) -18-methyl-19-nor-desA-androstan-5 i 17-dione yields the compound L3ß-ethyl-gon-4-eri-3,17-dione in the cyclization, which in turn can be selectively alkynylated using a suitable organometallic acetylide and norgestrel (13β-ethyl-17a-ethinyl-17-hydroxy-gon-4-en-3-one) supplies

Das Rohprodukt wird zwecks "i&inigung mit 65O ml einer 20^-igea Natriurnsulfitlösung gerührt, wobei das pH der Lösung durch Zusatz von Eisessig auf 6,5 eingestellt wird. Danach wird das pH durch Zusatz von 20^-igej« Natriumhydroxidlösung auf 7*5 gebracht. Man rührt eine weitere Stunde bei 40° und extrahiert das Reaktionsgernisch mit Aether. Die wässrige Schicht wird auf pH 12,5 durch Zusatz von 20^-iger Natronlauge gestellt und erneut mit Aether extrahiert. Abdampfen des Aethers liefert das reine Hemiacetal, 6-[4-Tertiärbutoxy-penty13-2-tetrahydropyranol, in flüssiger Form.the remaining 2 ^ 0 ml are added over the course of 1 hour. The reaction mixture is then refluxed for a further hour, cooled and filtered. The thus obtained Grignard solution becomes a solution of 59 g freshly distilled at -25 ° Glutaraldehyde was added to 400 ml of tetrahydrofuran. The mixture is stirred for a further 15 minutes at -25 ° and then holds Reaction mixture for 1 hour at 0 °. After the addition of 650 ml of 20% aqueous ammonium chloride solution, the pH of the solution is increased by I. Addition of 100 ml of 1 normal hydrochloric acid adjusted to 4. Extraction with ether yields 91 g of 6- [4-: tertiary butoxy-pentyi] ~ 2-tetrahydropyranol as an oily crude product. The crude product is cleaned with 65O ml of a 20% sodium sulfite solution stirred, the pH of the solution being adjusted to 6.5 by adding glacial acetic acid. Then the pH is adjusted by adding 20% sodium hydroxide solution brought to 7 * 5. One stirs one another hour at 40 ° and extracted the reaction mixture with Ether. The aqueous layer is adjusted to pH 12.5 by adding 20% sodium hydroxide solution and extracted again with ether. Evaporation of the ether gives the pure hemiacetal, 6- [4-tert-butoxy-penty13-2-tetrahydropyranol, in liquid form.
