Abstract: Polyalkylbenzene hydroperoxides are prepared from a homogeneous solution at increased rates in the presence of sulfolane from polyalkylbenzenes which are poorly soluble or insoluble in sulfolane by preoxidizing the polyalkylbenzene to an oxidation level of at least 10 percent and less than 55 percent. Then the sulfolane is added and a homogeneous solution is formed and oxidation is continued to produce a hydroperoxide product at increased rates and to excellent conversions.

Abstract: This invention comprises certain analogs of the prostaglandins in which the C-1 carboxyl is replaced by a primary alcohol. Also provided in this invention, are novel chemical processes useful in the preparation of the above prostaglandin analogs. These prostaglandin analogs exhibit prostaglandin-like activity, and are accordingly useful for the same pharmacological purposes as the prostaglandins. Among these purposes are blood pressure lowering, labor induction at term, reproductive-cycle regulation, gastric antisecretory action, and the like.

Abstract: A chain terpene alcohol having the formula ##STR1## wherein R.sup.1 and R.sup.2 are the same or different and respectively represent hydrogen atom or a lower alkyl group is produced by oxidizing a chain unsaturated amine having the formula ##STR2## wherein R.sup.3 represents an alkyl group and heating the product for a thermal rearrangement to form a chain unsaturated hydroxylamine having the formula ##STR3## and then reducing the chain unsaturated hydroxylamine with hydrogen in the presence of a catalyst selected from the group consisting of iron family elements, copper family elements, oxides thereof and copper chromite.

Abstract: Alpha-diketones, such as 1-phenyl-1,2-propanedione and 1-propyl-1,2-butanedione, are prepared by reacting an acylmethyl ester of a carboxylic acid (e.g., benzoylmethyl acetate or butanoylmethyl propionate) with an aldehyde, such as formaldehyde or acetaldehyde, in the presence of an acid catalyst and water. Such alpha-diketones are also obtained by first refluxing a mixture of an alpha-haloketone and a carboxyl anion source and then reacting the mixture with an aldehyde in the presence of an acid catalyst and water.

Abstract: Trans-N-acyl-N-alkyl-1-amino-1,3-butadienes are prepared by contacting a conjugated azomethine with a strong base in an inert organic solvent at sub-zero temperature and thereafter acylating the resulting product. The trans-N-acyl-N-alkyl-1-amino-1,3-butadienes are useful as intermediates in the formation of substituted decahydro-quinolines, Pumiliotoxin C, and can also be used as the diene in Diels-Alder reactions or can be copolymerized with vinyl compounds.
