Abstract: A process for the preparation of 3-(3,4-dihydroxyphenyl)-L-alanine (L-DOPA) wherein .alpha.-acetamido-4-hydroxy-3-alkoxy-cinnamic acid acetate is subjected to catalytic asymmetric hydrogenation to yield an optically active mixture N-acetyl-3-(4-hydroxy-3-alkoxyphenyl)-alanine acetate, with the L enantiomorph being present in a major amount and the D enantiomorph being present in a minor amount, from which N-acetyl-3-(4-hydroxy-3-alkoxyphenyl)-L-alanine acetate can be easily recovered and is then converted to L-DOPA.Novel precursors for L-DOPA are prepared in the process of this invention.

Abstract: The present invention relates to an improvement in a die for extruding thermoplastic sheet having a controlled degree of microsurface roughness. The improvement comprises having a beveled leading edge on at least one of the die lips wherein the bevel is away from the die orifice in order to control the degree of microsurface roughness in the extruded sheet.

Abstract: 1-(3'-Hexenyl)-1-cycloalkanols and their esters characterized by the structural formula ##SPC1##Wherein R represents hydroxyl or R.sup.1 COO--, wherein R.sup.1 represents alkyl having from 1 to 8 carbon atoms, aryl or aralkyl and n is an integer from 1 to 3. These compounds can be in the cis or trans forms or mixtures thereof. The compounds have very pleasant, strong and long lasting green, floral, rosy aromas and are useful as fragrances or as components in fragrance compositions.

Abstract: The performance of phosphorus-vanadium-oxygen catalysts useful for the conversion of saturated aliphatic hydrocarbons to maleic anhydride is dependent on the controlled calcination of the catalyst precursor. Phosphorus-vanadium-oxygen catalysts are prepared by mixing phosphorus and vanadium compounds to form precursors containing tetravalent vanadium, and calcining the precursors in an oxidizing atmosphere until a controlled level of pentavalent vanadium has been achieved, and then calcining the precursors in an inert atmosphere to higher temperatures to provide catalysts with the desired oxidation levels that are promptly active, so that valuable manufacturing facilities are not required to "activate the catalyst.

Abstract: 2-Alkyl-oct-5-en-2-ols and their esters characterized by the structural formula ##EQU1## wherein R represents alkyl having from 1 to 8 carbon atoms and R.sup.1 represents hydroxyl or R.sup.2 COO--, wherein R.sup.2 represents alkyl having from 1 to 8 carbon atoms, aryl or aralkyl. These compounds can be in the cis or trans forms or mixtures thereof. The compounds have very pleasant, strong and long lasting green, floral, rosy aromas and are useful as fragrances or as components in fragrance compositions.

Abstract: 4-(2'-norbornyl)-2-butanones characterized by the structural formula ##SPC1##Wherein R.sup.1 represents hydrogen or methyl, and R represents hydrogen or a lower alkyl group are prepared by a crossed aldol condensation of 5-norbornene-2-carboxaldehyde or norbornane-2-carboxaldehyde with methyl ketones in a basic medium followed by a subsequent dehydration of the aldol formed to prepare the 3-buten-2-ones which are subsequently hydrogenated. The compounds have very pleasant, strong and long lasting woody odors and are useful as compounds in fragrance compositions.
