, (2020/12/01)
Two kinds of Schiff bases, 85 samples of N-(benzylidene)-anilines (ZBAY) and 83 samples of N-(phenyl-ethylene)-anilines (ZAPEY), were used as model compounds, in which the ZBAY contains 13 compounds with 2-OH and the ZAPEY contains 35 compounds with 2-OH

Abstract: In the study, a series of new 3-aryl-1,3-benzoxazine-2-ketone derivatives hasbeen designed, synthesized and evaluated for anti-fungal activity against sixspecies of phytopathogenic fungi. Among those, two compounds have exhibited highinhibitory
Oxazine Ring-Related Vibrational Modes of Benzoxazine Monomers Using Fully Aromatically Substituted, Deuterated, 15N Isotope Exchanged, and Oxazine-Ring-Substituted Compounds and Theoretical Calculations

Polymerization of benzoxazine resins is indicated by the disappearance of a 960-900 cm-1 band in infrared spectroscopy (IR). Historically, this band was assigned to the C-H out-of-plane bending of the benzene to which the oxazine ring is attach
Copper-Catalyzed Cascade Cycloamination of α-Csp3-H Bond of N-Aryl Ketimines with Azides: Access to Quinoxalines

supporting information, p. 2078 - 2081 (2016/06/01)
A copper-catalyzed cycloamination of α-Csp3-H bond of N-aryl ketimines with sodium azide has been developed. This methodology provides an efficient access to quinoxalines and features mild reaction conditions and readily available ketimines with diverse functional group tolerance.

Asymmetric reduction of aryl imines using Candida parapsilosis ATCC 7330
Vaijayanthi,Chadha, Anju
, p. 93 - 96 (2008/09/17)
A highly enantioselective one pot, novel biocatalytic method for the asymmetric reduction of aryl imines is reported. Treatment of aryl imines with Candida parapsilosis ATCC 7330 in aqueous medium produces the enantiomerically pure (R)-secondary amines in
The novel reaction of ketones with o-oxazoline-substituted anilines
Luo, Fen-Tair,Ravi, Vija K.,Xue, Cuihua
, p. 9365 - 9372 (2007/10/03)
A variety of ketones react with o-oxazoline-substituted anilines in the presence of catalytic amount of p-toluenesulfonic acid in dry n-butanol to form 4-amino-substituted quinolines or 4-quinolones in fair to good yields.
A study of the gas-phase interconversion of 1-(2-aryloxyphenyl)-alkaniminyl and 2-(aryliminomethyl)phenoxyl radicals

Flash vacuum pyrolysis of the allyl ethers 9-11 and of the oxime ethers 15-17 at 650°C (5 × 10-2-5 × 10-3 Torr) generates 2-(aryliminomethyl)phenoxyl radicals 4 and 1-(2-aryloxyphenyl)alkaniminyl radicals 5 respectively which can interconvert via a spirodienyl radical leading to common products which are generally isolated in low to moderate yield. The iminyls 5 normally undergo β-cleavage leading to nitriles (e.g. 21) and/or to benzofurans (e.g. 22) after cyclisation. The phenoxyls 4 show more complex behaviour dominated by hydrogen abstraction processes leading to products such as phenols (e.g. 32), the indole 27 or phenanthridines 34 and 35.
New Route for the Preparation of 2H-3-Aryl-3,4-dihydro-1,3-benzoxazines and 2H-3-Aryl-3,4-dihydro-4-methyl-1,3-benzoxazines

2-Hydroxybenzaldehyde (1) and 1-(2-hydroxyphenyl)ethanone (2) on reaction with different primary aromatic amines gave 2-(arylimino)methylphenols (3) and 2-phenols (4), respectively. 3 and 4 on reduction with sodium borohydride gave 2-(arylamino)methylphenols (5) and 2-phenols (6), which underwent cyclisation with formaldehyde to form 2H-3-aryl-3,4-dihydro-1,3-benzoxazines (7) and 2H-3-aryl-3,4-dihydro-4-methyl-1,3-benzoxazines (8), respectively.
