Crystal structure of (±)-3-[(benzo[d]- [1,3]dioxol-5-yl)methyl]-2-(3,4,5-trimethoxyphenyl)- 1,3-thiazolidin-4-one
(International Union of Crystallography - IUCrChester, 2014-12)
In the title thiazolidine-4-one derivative, C20H21NO6S, the central thiazolidine ring is essentially planar (r.m.s. deviation for all non-H atoms = 0.0287 Å) and forms a dihedral angle of 88.25 (5)° with the methoxy-substituted ...
Synthesis and Evaluation of the Fungal Activity of New Pyrazole-Carboxamides against Colletotrichum gloeosporioides
(Sociedade Brasileira de Química, 2020-05)
The pyrazole core has been recognized by their biological properties and included in the synthesis of modern agrochemicals. Part of these studies consists of making structural modifications to pesticides for commercial ...
New synthesis of naphtho- and benzoxazoles: Decomposition of naphtho- and benzoxazinones with KOH
(MARCEL DEKKER INC, 2001)
A method that allows the synthesis of 4 different heterocyclic systems of fused aryl oxazoles, i.e., naphtho[1,2-d], naphtho[2,1-d], naphtho[2,3-d], and benzo[d]oxazoles in reasonable yield is del scribed. This method ...
Photosensitized generation of singlet molecular oxygen by aryloxazinones
