Title: Improvements in or relating to oxapregn-4-ene-3,20-diones and compounds related thereto
IPC: C07J75/00
Filed: 1962-11-06
Abstract: The invention comprises compounds of the formula: <FORM:0966072/C1/1> (wherein A is methylene or ethylene, R is hydrogen or alkanoyloxy of 1 to 6 carbon atoms and R1 is hydrogen or methyl) and the 4,5-dehydro, 4a ,5-dehydro and 4,5:6,7-bisdehydro derivatives thereof, and the corresponding hydroxy-acids and salts thereof; and their preparation by reduction of compounds of the formulae: <FORM:0966072/C1/2> and <FORM:0966072/C1/3> (wherein M is hydrogen or an ammonium or alkali metal cation, the dotted lines are optional 4(5), 4a(5) and 4(5), 6(7) double bonds, and R11 is a b -hydrogen atom or, when there is no 6(7) double bond, a hydroxy radical) by use of a metallic reagent capable of reducing a formyl group to a carbinol group followed by, when R11 is OH, dehydration, and when the 20-oxo group has been reduced to a hydroxy group, oxidation of this group. Double bonds may also be reduced in this process or they may be subsequently reduced or introduced. In a modification, 6-acyloxy compounds are used in the reduction process and subsequently hydrolysed.  Dehydration may result in a 5,6-dehydro-lactone which is then isomerized to the corresponding 4,5-dehydro-lactone. The lactones of the invention are stated to be in equilibrium with the corresponding hydroxy-acids in solution. Examples are given. Compounds of formula III wherein R11 is hydrogen are prepared by hydroxylating appropriate pregna-1, 4-diene-3, 20-diones to the corresponding 1,2-diols and cleaving these to give 1,2-seco-A-norpregn-3-en-2-oic acids which may be hydrogenated to the corresponding 1,2-seco-A-norpregnan-2-oic acids. Compounds of formula III wherein R11 is hydroxy and R is alkanoyloxy are prepared by epoxidising a 17a -alkanoyloxy-3b -hydroxy-pregn-5-en-20-one, reacting the 5,6-epoxide so formed with acetone in aqueous chromic acid to give the corresponding 17a -alkanoyloxy-5a , 6b -dihydroxy-pregnane-3, 20-dione or with chromium trioxide in pyridine (used on the a -epoxide) to give the corresponding 17a - alkanoyloxy -6a - hydroxy-pregn -4- ene -3, 20-dione, reacting either of these products with dichlorodicyano benzoquinone to yield the corresponding 17a -alkanoyloxy-6a  or b -hydroxy-pregn-1, 4-diene-3, 20-diones and then hydroxylating these and cleaving the 1,2-glycols so formed.  The products may then be hydrogenated to give the 4,5-saturated compounds or dehydrated to give the 6(7)-unsaturated compounds. Compounds of formula IV are prepared by converting pregn-4-ene-3, 20-diones to the corresponding 2a -hydroxy-pregn-4-ene-3, 20-diones (either via the 6-bromo- and then the 2a -acetoxy-compounds or directly via the latter), and reacting these with periodic acid in aqueous pyridine.

The sensing element of a rotary fluid flowmeter comprises a bladed rotor 14, mounted for rotation in a conduit 11 in which fluid normally flows in one direction and vanes 33 downstream of the rotor blades 24 which can impart rotation to a fluid flowing in an opposite direction, whereby the rotational effect of the said opposite flow upon the rotor is largely reduced. The spindle of the rotor is mounted in polyfluorethylene bushes 17 and 27 supported in the conduit on radial arms 19 and 29. The vanes 33 are helically twisted and overlap part of the rotor 14 downstream of the blades 24. A magnet 25 in the rotor is magnetised across a diametral plane of the latter so that its rotation generates a current in a coil (not shown) in a recess 26 in the housing 10, the frequency of the current being a direct puncture of the rotational speed of the rotor and measurable by a frequency meter. The meter is intended for measuring the flow of potable fluids, e.g., milk and the reverse flow of, e.g., steam cleanses the motor. The purpose of the device disclosed is to prevent the reverse flow of these from rotating the rotor at such a speed that it will be damaged.
