Title: A process for the preparation of forskolin from 9-deoxy-forskolin and intermediates used therein
Inventor: HRIB NICHOLS J
IPC: A61K31/35
Filed: 1987-03-27
Abstract: A method of regioselectively and stereoselectively synthesizing forskolin (8,13-epoxy-1 alpha ,6 beta ,7 beta ,9 alpha -tetrahydroxylabd-14-en-11-one) from 9-deoxyforskolin (8,13-epoxy-1 alpha ,6 beta ,7 beta ,-trihydroxylabd-14-en-11-one) with a good yield is described. In a preferred embodiment, it comprises an enol ether formation from 8,13-epoxy-1 alpha ,6 beta ,7 beta -trihydroxylabd-14-en-11-one-6,7-carbonate, oxidation of the enol ether with a suitable peroxy acid to obtain 11,12-dehydro-8,13-epoxy-11-methoxy-1 alpha ,6 beta ,7 beta ,9 alpha -tetrahydrolabd-14-ene-6,7-carbon ate and hydrolysis of the latter under an acidic condition to obtain 8,13-epoxy-1 alpha ,6 beta ,7 beta ,9 alpha -tetrahydroxylabd-14-en-11-one-6,7-carbonate. As an alternative way of protecting the two hydroxy groups at carbon-6 and carbon-7, they may also be converted to dimethyl acetal during the synthetic sequence. Four compounds produced in the synthetic scheme as intermediates, namely, 9,11-dehydro-8,13-epoxy-11-methoxy-1 alpha ,6 beta ,7 beta -trihydroxy-labd-14-ene-6,7-carbonate and 11,12-dehydro-8,13-epoxy-11-methoxy-1 alpha ,6 beta ,7 beta ,9 alpha -tetrahydroxylabd-14-ene-6,7-carb onate and the corresponding dimethyl acetal compounds are believed to be novel.

Title: Porous ceramic composite with dense surface
IPC: C04B35/65
Filed: 1987-07-07
Abstract: There is disclosed a method for making a self-supporting ceramic composite article having a porous core bearing a dense surface layer formed integrally with said core. A preform comprises a filler material and parent metal distributed therethrough, wherein the volume percent of parent metal is sufficient to form a volume of oxidation reaction product exceeding the total volume available within said preform. The parent metal is molted and reacted with an oxidant to form an oxidation reaction product filling the spatial volume and leaving voids. The reaction is continued to further transport molten parent metal through the oxidation reaction product to at least one surface of the preform to form oxidation reaction product on said surface substantially free of voids thereby forming a relatively dense surface layer.

Title: Mold for electromagnetic continuous casting
IPC: B22D11/04
Filed: 1988-03-16
Abstract: An electromagnetic mold for vertical continuous casting of rolling slabs, featuring an inductor and an electromagnetic screen partly covering the induction is such that the vertical distance between the lower edge of the inductor and the lower edge of the screen is greater at the narrow sides of the mold than at the broad sides of the mold. As a result of this arrangement it is possible to prevent metal running out of the ingot head at the narrow sides during the start-up phase. The foregoing is achieved at the expense of an insignificant amount of melt circulation occurring in the molten head of the ingot.

Title: Method of making silicon quantum wires
Inventor: CANHAM LEIGH-TREVOR
IPC: H01L29/06
Filed: 1992-05-01
Granted: 1994-07-20
Abstract: Luminescent silicon incorporating semiconductor quantum wires is made using a semiconductor wafer 14 as starting material. The wafer 14 is weakly doped p type with a shallow heavily doped p layer therein for current flow uniformity purposes. The wafer 14 is anodised in 20% aqueous hydrofluoric acid to produce a layer 5  mu m thick with 70% porosity and good crystallinity. The layer is subsequently etched in concentrated hydrofluoric acid, which provides a slow etch rate. The etch increases porosity to a level in the region of 80% or above. At such a level, pores overlap and isolated quantum wires are expected to form with diameters less than or equal to 3 nm. The etched layer exhibits photoluminescence emission at photon energies well above the silicon bandgap (1.1 eV) and extending into the red region (1.6 - 2.0 eV) of the visible spectrum.
