4-π-Photocyclization of 1,2-Dihydropyridazines: An Approach to Bicyclic 1,2-Diazetidines with Rich Synthetic Potential.

The 4-π-photocyclization of a range of 1,2-dihydropyridazines is described, generating bicyclic 1,2-diazetidines in high yields on multigram scale. The key bicyclic 1,2-diazetidines are versatile synthetic intermediates and were easily converted into a range of novel derivatives, including functionalized 1,2-diazetidines, cyclobutenes, cyclobutanes, and 1,3-dienes

Hydrodinamic Aspects of a High-Speed SWATH and New Hull Form

The main problems of high-speed ships operating in open seas are their insufficient seaworthiness and speed loss in high sea states. Small Water-plane Area Twin-Hulls (SWATH) are characterised by excellent seaworthiness, but the hull forms of a traditional SWATH are not suited for higher speeds. A new shape of underwater gondola has been developed for a semi-planing (S/P) SWATH. Additionally, hydrofoils can be applied to this ship to provide the optimal dynamic draught and trim, to mitigate motions in rough seas, and even to carry a part of the ship weight. The relative speed of this SWATH can be beneficially increased up to the displacement Froude number 3. Several concept designs addressing naval and civil transportation needs are outlined in this paper

Preparation, characterization and in vitro antioxidant and cytotoxicity studies of some 2,4-dichloro-N-[di(alkyl/aryl)carbamothioyl]benzamide derivatives

Abstract In the present study, three biologically active, substituted acyl thiourea compounds (1–3) have been synthesized from 2,4-dichlorobenzoyl chloride, potassium thiocyanate and the corresponding secondary amine in dry acetone. As analytical and spectral data of 1 and 3 have already been discussed in the literature, only the compound 2 was characterized by elemental analyses, UV–Visible, FT–IR, 1H & 13C NMR spectroscopic techniques. The molecular structures of 1–3 were determined by single crystal X-ray crystallography which shows twists of up to 70° about the (S=)C–NC(=O) bonds. All the synthesized compounds show good antioxidant property and cytotoxic potential against Ehrlich Ascites Carcinoma (EAC) cancer cell line
