Reactions concerned in Tertiary Amine N-Oxides. IV. Reactions of 6-Methyl-4(3H)-Pyrimidinone and 4(3H)-Quinazolinone with Pyridine N-Oxide

Application of Water for Synthesis of Cyclopentadienes via Multi-component Reactions of N-methyl imidazole

A water-accelerated multi-component synthesis of organic target molecules was used as a key method for the preparation of cyclopentadiene derivatives. The three-component condensation reactions of primary amines with alkyl propiolates in the presence of N-methylimidazole in water at room temperature were developed as efficient and clean green synthetic procedures for the high-yielding preparati...

6-Chloro-N-methyl-5-nitro-N-phenyl­pyrimidin-4-amine

In the title compound, C(11)H(9)ClN(4)O(2), the dihedral angle between the aromatic rings is 79.67 (8)°. π-π stacking between centrosymmetrically related pairs of pyrimidine rings occurs along [100] [centroid-centroid separations = 3.4572 (8) and 3.5433 (7) Å].

Gold-catalysed cycloisomerisation reactions of 2-(2-propynyl)pyridine N-oxides leading to indolizinones.

Gold(I)-catalysed tandem oxygen-transfer/cycloisomerisation reaction of 2-(2-propynyl)pyridine N-oxides provides an atom-economical route to indolizinone frameworks.

N-methyl-N'-nitro-N-nitrosoguanidine: reactions of possible significance to biological activity with mammalian cells.

4-Chloro-6-methyl-N-(4-methyl­phen­yl)quinolin-2-amine

In the title compound C(17)H(15)ClN(2), the dihedral angle between the quinoline ring system and the phenyl ring is 50.18 (6)°. In the crystal, mol-ecules are linked into chains running along the c axis by N-H⋯N hydrogen bonds.
