The following intermediates are also prepared; compounds of the formulµ where R<SP>10</SP> and R<SP>11</SP> are C 1-5 alkyl where X is halogen and Z<SP>1</SP> is (CH 2 ) n where n is 1 to 4, where R<SP>12</SP> is H, C 1-4 alkyl or CH 2 CF 3 ; where R<SP>52</SP> is H, C 1-4 alkyl or CH 2 CF 3 or R<SP>52</SP> and R<SP>3</SP> are joined together to form, with the intervening carbon atoms a C 5-9 carbocyclic ring; 1 - nonen - 4 - ol, 4 - acetoxy - 1 - nonene, 2 - methyl - 2 - hydroxy - 3 - (6 - carboxyhexyl) - 6 - hexyltetrahydropyran; where X<SP>1</SP> is Cl or OH; dimethyl 3-oxosebacoate, 1-chloro 3 -octanol; 3-chloromethoxy-1-chlorooctane; 3-benzyloxy-1-chlorooctane; methyl- 8 - oxo - 9 - methoxycarbonyl - 12 - benzyloxyheptadecanoate; 8-oxo-12-benzyloxyheptadecanoic acid; 3-chloromethoxy-1-bromopropane; 3-benzyloxy-1-bromopropane; 8-(3- benzyloxypropylidenyl) - 12 - benzyloxyheptadecanoic acid; 8-(4-benzyloxynonyl)-8,9-epoxy- 11-benzyloxyundecanoic acid; 8-(3-benzyloxypropionyl) - 12 - benzyloxyheptadecanoic acid; 5-acetoxypentyl chloride; diethyl 2-(5-acetoxypentyl) - 2 - methylmalonate; 7 - bromo - 2- methylheptanoic acid, and its methyl ester; 8- (3 - benzyloxy - 1 - hydroxypropyl) - 12 - benzyloxyheptadecanoic acid; 8-(3-methoxy-1-bydroxypropyl) - 12 - hydroxyheptadecanoic acid; 8,12 - dihydroxyheptadecanoic acid; ethyl ethyl 4-bromobutoxyacetate; N-t-butyl-3-(8- acetyl - 12 - hydroxyheptadecanoyloxy)crotonamide; ethyl 8-diazoacetyl-12-acetoxy-heptadecanoate; 3-acetoxy-1-octyne; 1-diethylamino - 4 - acetoxy - 2 - nonyne; 1-bromo- 4 - acetoxy - 2 - nonyne; diethyl 2 - acetyl- 2 - (4 - acetoxy - 2 - nonynyl)azelate; 8- acetyl - 12 - oxo - heptadecanoic acid; 1- acetoxy - 1 - ethynylcyclohexane, 1 - acetoxy- ] - ethynylcyclooctane; 1 - acetoxy - 1 - (3- diethylamino - 1 - propynyl)cyclohexane; 1- acetoxy - 1 - (3 - diethylamino - 1 - propynyl)-cyclooctane; 1 - acetoxy - 1 - (3- bromo - 1 - propynyl)cyclohexane; and 1- acetoxy - 1 - (3 - bromo - 1 - propynyl)cyclooctane. (3 - Benzyloxypropyl)triphenylphosphonium bromide is obtained by reacting 3-benzyloxy-1- bromopropane with triphenylphosphine. Pharmaceutical compositions suitable for oral, parenteral, rectal or topical administration, contain the above 11,12-secoprostaglandins and pharmaceutically acceptable carriers. The compositions are used to improve renal function, the treatment of hypertension and dwarfism, and prevention of thrombus formation.n[GB1431100A] |
