Paragraph 0394, (2021/07/31)
Provided herein are novel heterocyclic compounds, for example, compounds having Formula I, I-P, II, lI-P, or III. Also provided herein are pharmaceutical compositions comprising the compounds and methods of using the same, for example, in inhibiting aldehyde dehydrogenases and/or for treating various cancers, cancer metastasis, type 2 diabetes, pulmonary arterial hypertension (PAH) or neointimal hyperplasia (NIH).

A photoredox and Br?nsted acid synergistically catalyzed cross-dehydrogenative C?O coupling reaction is developed in which isochroman peroxyacetals are formed through sp3 C?H bond peroxidation. The reported method is characterized by its extremely mild reaction conditions, excellent yields, and broad substrate scope. An oxocarbenium ion p-chlorobenzenesulfonate was speculated to be the reactive intermediate. The role of hemiacetals and oxygenated dimers on the effective stabilization of the oxocarbenium ion was investigated; the presence of acid appeared to establish equilibrium between hemiacetals and oxygenated dimers with the oxocarbenium ion pairs. The broad applicability of the method highlights the potential of the protocol for molecule synthesis.

Page/Page column 142, (2011/02/18)
Disclosed is a harmful arthropod control composition comprising, as an active ingredient, a fused heterocyclic compound represented by formula (1) [wherein A1 and A2 independently represent a nitrogen atom or the like; R1 and R4 independently represent a halogen atom or the like; R2 and R3 independently represent a halogen atom or the like; R5 and R6 independently represent a linear C1-C6 hydrocarbon group which may be substituted, or the like (provided that both R5 and R6 cannot represent a hydrogen atom simultaneously); and n represents 0 or 1]. The harmful arthropod control composition has an excellent efficacy to control harmful arthropods.
