Dies geht aus folgenden hervor:This can be seen from the following:
a) In der FR-PS 2 104 916 wurde ein Verfahren zur Synthese von Prostaglandin Ap der Formel I1 beschrieben.a) In FR-PS 2 104 916 a process for the synthesis of prostaglandin Ap of the formula I 1 was described.
Diese Synthese wird in 8 Stufen, ausgehend von Produkten der Formel:This synthesis is carried out in 8 steps, starting from products of the formula:
AIkO2CAIkO 2 C
durchgeführt, in der Alk einen niedrig-Alkylrest bedeutet und AIk1 einen Alkylrest darstellt, η eine ganze Zahl, nämlich 2, 3 oder 4,bedeutet und m eine ganze Zahl, nämlich 3, 4 oder 5, bedeutet.carried out in which Alk is a lower-alkyl radical and AIk 1 is an alkyl radical, η is an integer, namely 2, 3 or 4, and m is an integer, namely 3, 4 or 5.
Überdies enthält diese Synthese eine Stufe, die eine Tren nung der beiden Isomeren der Formeln:In addition, this synthesis contains a step that separates the two isomers of the formulas:
)0H) 0H
(CH2)n-C02H und(CH 2 ) n -C0 2 H and
08882/108708882/1087
die während der Behandlung in der Wärme des Produkts der Formel:which during treatment in the warmth of the product of the formula:
OCHOCH
(CH2)m-CH5 (CH 2 ) m -CH 5
erhalten werden, erforderlich macht.is required.
b) In der FR-PS 2 085 654 wurde eine Synthese in 3 Stufen des Dihydroprostaglandxns A2, ausgehend von Produkten der Formel B, beschrieben.b) In FR-PS 2 085 654 a synthesis in 3 stages of the dihydroprostaglandxn A 2 , starting from products of the formula B, was described.
Demgegenüber beschreibt die vorliegende Erfindung eine Synthese von Prostaglandin A„ in 2 Stufen, ausgehend von Dihydroprostaglandin A-· Diese Synthese ist somit kürzer als die in der FR-PS 2 104 916 beschriebene. Außerdem ist sie leichter durchführbar, da sie es gestattet, Trennungen von Isomeren zu vermeiden. Schließlich gestattet es die erfindungsgemäße Synthese, das Prostaglandin A_ mit einer überlegenen Gesamtausbeute, ausgehend vom Produkt B, zu erhalten.In contrast, the present invention describes a synthesis of prostaglandin A "in 2 stages, starting from dihydroprostaglandin A- · This synthesis is thus shorter than that described in FR-PS 2 104 916. It is also easier to carry out, as it makes it possible to avoid separations of isomers. Finally, the synthesis according to the invention allows starting the prostaglandin A_ with a superior overall yield from product B.
In anderer Hinsicht besitzt das erfindungsgemäße Verfahren ebenfalls zwei bedeutende Vorteile im Vergleich zu dem in J.A.C.S., 98_, 6 (1976), S. 83 beschriebenen Verfahren, das darin besteht, ein Prostaglandin Ap, ausgehend von einem Derivat des Dihydroprostaglandins A-, durch Verwendung von Phenylselenylchlorid herzustellen.In other respects, the inventive method has also two significant advantages compared to the method described in J.A.C.S., 98_, 6 (1976), p. 83, the consists in a prostaglandin Ap, starting from a derivative of dihydroprostaglandin A-, by using phenylselenyl chloride to manufacture.
In der Tat wird die in J.A.C.S. beschriebene Synthese in 4 Stufen durchgeführt, während diejenige der vorliegenden Erfindung nur zwei benötigt. Überdies verwendet die in J.A.C.S. beschriebene Synthese ein toxisches Reagens, während das beiIndeed, the J.A.C.S. synthesis described in 4 steps are carried out while that of the present invention requires only two. In addition, the J.A.C.S. synthesis described a toxic reagent, while that in
709882/1097709882/1097
der erfindungsgemäßen Synthese verwendete Reagens nicht toxisch ist.reagent used in the synthesis of the present invention is non-toxic is.
