Gold(III) chloride catalysed synthesis of 5-alkylidene-dihydrothiazoles.
A two step synthesis of dihydrothiazoles is presented. First, the previously unknown N-propargylic dithiocarboimidates are produced in good yields from easily available, cheap starting materials. The subsequent gold catalysed ring closure is fast and efficient, leading to dihydrothiazoles through a cascade of 5-exo-dig cyclisation and 1,3-alkyl migration. The yields range from 74% to 95%.
متن کاملAn expeditious synthesis of [1,2]isoxazolidin-5-ones and [1,2]oxazin-6-ones from functional allyl bromide derivatives.
Reaction of allyl bromide (Z)-1 and (Z)-2 with N-substituted hydroxylamine hydrochlorides in presence of tert-butoxide in tert-butanol at reflux provides a short and effective route to [1,2]isoxazolidin-5-ones 3 and [1,2]oxazin-6-ones 4.
متن کامل5-6-7 Meshes
We introduce a new type of meshes called 5-6-7 meshes. For many mesh processing tasks, lowor high-valence vertices are undesirable. At the same time, it is not always possible to achieve complete vertex valence regularity, i.e., to only have valence-6 vertices. A 56-7 mesh is a closed triangle mesh where each vertex has valence 5, 6, or 7. An intriguing question is whether it is always possible...
متن کاملSynthesis of 5 - Methoxycarbonyl - 1 l - methylfuro ( 2 , 3 - c ) acridan - 6 ( 11 H ) ones
The plant family Rutaceae is known [1, 2] to be a prolific source of furoquinoline and pyranoquinoline alkaloids. Along with them acridine alka loids [3, 4] have also been isolated from several members of the same plant family. Recently furanfused acridine systems such as 1 l-methylfuro(2,3-c)acridan-6(l lH)one (1) have also been reported [5-7] to occur in some rutaceous plants. Typical exampl...
متن کاملSynthesis of Ru alkylidene complexes
The present work describes the robust synthesis of Ru alkylidene complexes (PCy(3))(2)Cl(2)Ru=CHR - precursors for metathesis catalysts. Moreover, the dynamic behavior of complexes where R = 2-naphthyl and 2-thienyl was studied. (1)H NMR techniques were employed to establish the preferred conformations in solution for both complexes and the energy barrier for rotation around single (Ru=)CH-C(th...
