1
represents a nitrogen atom or a group represented by formula CR
6
; A
2
and A
3
are the same as or different from each other and independently represent a nitrogen atom or a group represented by formula CH; R
1
represents an aryl group which may be substituted by 1 to 5 substituents independently selected from a substituent group (2) or the like; R
2
and R
3
are the same as or different from each other and independently represent a hydrogen atom, a halogen atom, a C
1-6
alkyl group, a C
1-6
haloalkyl group or a C

alkoxy group; and R
4
and R
5
are the same as or different from each other and independently represent a hydrogen atom, a C
1-6
haloalkyl group, a C
1-6
alkyl group or the like) or a salt thereof is useful as an anti-fungal agent.

Reactions between 1-nitroso-2-naphthols and α-functionalized ketones such as α-bromo-, α-chloro-, α-mesyloxy-, α-tosyloxy-, and α-hydroxy ketones under basic conditions delivered 2-substituted naphtho[1,2-d][1,3]oxazoles in a single synthetic operation. The product formation was accompanied by the unexpected loss of the C═O group from the α-functionalized ketones. With aryl bromides, allyl bromides
1-亚硝基-2-萘与α-官能化酮如α-溴代,α-氯代,α-甲氧基,α-甲苯磺酰基和α-羟基酮之间的反应在碱性条件下产生了2-取代的萘并[一次合成操作中的1,2- d ] [1,3]恶唑。产物的形成伴随有α-官能化酮中C═O基团的意外损失。以芳基溴化物,烯丙基溴化物,α-溴二酮,α-溴氰化物,α-溴酸酯和α-溴酮酸酯为底物,还观察到了萘并[1,2- d ] [1,3]恶唑的形成。在回流下在1,2-二氯乙烷或乙腈中进行转化,得到相应的萘并恶唑,产率在52%至85%之间。

FAD-dependent enzyme mono-amine oxidase A (MAO-A). Although a wide range of irreversibleinhibitors of LSD1 have been reported with activities in the low nanomolar range, this work represents one of the first reported examples of a reversible small molecule inhibitor of LSD1 with clear SAR and selectivity against MAO-A, and could provide a platform for the development of more potentreversibleinhibitors.
