We report a phosphine-mediated direct β-acylation of α,β-unsaturated 1,3-diketones with acyl chlorides and a base. Functionalized furanones were also prepared by the reaction of cinnamic acid and acyl chloride according to our protocol via β-acylation. Our studies revealed that α,β-unsaturated 1,3-diketones with an electron-donating group at the second position favor the formation of β-acylated products, whereas those with oxygen, such as anhydrides, favor furanones via an unprecedented C-acylation/cyclization sequence.

An array of 2-substituted-4,5-diphenyloxazoles were found to be cleaved to triacylamines and diacylamines (imides) using a reagent system composed of m-chloroperbenzoic acid (MCPBA) and 2,2′-bipyridinium chlorochromate (BPCC). The 2-alkyl-4,5-diphenyloxaz

Nitrosocarbonyl intermediates are photochemically generated from 1,2,4- oxadiazole-4-oxides and efficiently trapped with enes and dienes.

There are provided novel enterobactin type compounds. There is provided a novel process for the production of enterobactin, and of novel enterobactin type compounds which process is based on the reaction of a serine derivative with a stannoxane of the [BU2 Sn(OCH2 CH2 O)] type. Enterobactin is a known compound of known utility. The novel derivatives are valuable as sequestering agents for iron and other transition metals, for the separation and analysis of same. They can be used as active ingredients in pharmaceutical compositions for the removal of such metals accumulated above an acceptable level in patients.

Phenylmagnesium bromide reacts with 3-chloro-5,6-diphenyl-1,2,4-triazine (I) to give eleven products (II-XI and an undefined product with m.p. 270 deg C).A suitable mechanism for their formation has been discussed.
