Improved Synthesis of Vasicinone

A new, high yielding method for the preparation of vasicinone (7) is described. Reaction of 2-nitrobenzoic acid with N, N¢-carbonyldiimidazole followed by 2-pyrrolidinone gave 1-(2-nitrobenzoyl)pyrrolidine-2-one (3). Reduction of the latter with 10% Pd-C afforded deoxyvasicinone (4). Reaction of deoxyvasicinone (4) with bromine yielded monobromo-deoxyvasicinone (5). Exchange of bro...

An improved method for 2-D self-similar image synthesis

We propose a new method called incremental Fourier synthesis to generate 2-D self-similar images based on a 2D fractional Brownian motion (fBm) model. With this method, the stationary increments of fBm are created by a Fourier synthesis method and the increments are added up to generate the nonstationary 2D fBm process. Since the new method takes advantage of the FFT, its computational complexi...

An improved synthesis of octaethylporphyrin.

Octaethylporphyrin (OEP, 1) is, by reason of its symmetry, high solubility, and stability, one of the more important and widely used models for the study of porphyrin chemistry. In the past, its synthesis has been tedious and erratic, particularly whenever more than a few grams were required. The usual syntheses, those of Inoffen et al. l and of Whitlock and Hanauer2 (based on earlier work of E...

An Improved Synthesis of Homocitrate

Monoethyl malonate (1) and tert-butyl alcohol are esterified by catalysis with dicyclohexylcarbodiimide and 4-dimethylaminopyridine to yield ethyl t-butyl malonate (2). The ethoxymagnesio derivative (3) of the ester is condensed with β-carbomethoxypropionyl chloride to give the triester (4), which is decomposed by heating under vacuum in the presence of β-naphthalensulfonic acid to give ethyl m...
