Hypervalent Iodine(III)‐Mediated Benzannulation of Enamines with Alkynes: an Efficient Synthesis of Substituted Aminonaphthoic Acid Derivatives

Chinese Journal of Chemistry (2015)

Peng Gao Mingjin Fan Zijing Bai Yunyang Wei

Abstract An intermolecular two CC bond formation procedure for the synthesis of carbocycles mediated by hypervalent iodine(III) reagents was developed. This metal free protocol provided a new approach for the synthesis of useful substituted 1‐amino‐2‐naphthoic acid derivatives via benzannulation reactions. Various N ‐unsubstituted and N ‐alkyl substituted aromatic enamines with terminal alkynes and non‐terminal alkynes can be converted into corresponding 1‐amino‐2‐naphthoic acid derivatives under mild reaction conditions. When meta‐substituted phenyl enamines were employed in the reaction, two cyclization paths were detected in the reaction and ortho ‐cyclization products were the only or major products. Good functional group tolerance, readily available material and high atom utilization efficiency make this method a potential procedure which may find broad application in organic synthesis.

Hypervalent Iodine(III)-Mediated Benzannulation of Enamines with Alkynes for the Synthesis of Polysubstituted Naphthalene Derivatives

Organic Letters (2013)

Peng Gao Jinjian Liu Yunyang Wei

A series of functionalized 1-amino-2-naphthalenecarboxylic acid derivatives were synthesized from enamines and alkynes via a benzannulation strategy mediated by iodosylbenzene and BF3·Et2O. The advantages of this novel benzannulation process include broad substrate scope, good functional group tolerance, and mild reaction conditions without the use of heavy metals.

Homogeneous Degradation of Cotton Cellulose into Furan Derivatives in ZnCl₂Solution by Integration Technology of Reaction and Extraction

Industrial & Engineering Chemistry Research (2012)

Xiao‐Na Lv Gang Li Fang Yang Peng Gao Zhihua Liu

This study has investigated homogeneous degradation of cotton cellulose into furan derivatives, namely 5-hydroxymethylfurfural (HMF), 1-(furan-2-yl)-2-hydroxyethanone (FHE), and furfural (FF), in concentrated zinc chloride solution under biphasic reaction system with Lewis acids (ZnCl2) as catalysts. Compared with cellulose degradation in pure aqueous phase without any organic solvent, using the integrated reaction and extraction process has shown significant enhancement for the production of HMF, FF, and FHE although the effect on the HMF yield is most significant. However, when dimethyl sulfoxide (DMSO) was added either in the reactive phase or in the extractive phase, the FHE production was inhibited but other product yields were increased. By optimizing the operation conditions, the maximum yields of HMF and FF have been achieved as 79.68 and 17.02 g/kg cellulose. These product yields were, respectively, 130.84 and 3.29 times of those obtained from the systems without any extraction solvent.

The Formation Mechanism of Impulse Buying in Short Video Scenario: Perspectives From Presence and Customer Inspiration

Frontiers in Psychology (2022)

Peng Gao Yuanyuan Zeng Yu Cheng

It has been found in many cases that consumers are prone to exhibit impulsive buying behavior that is manifested as being immediate, emotional, and irresponsible especially under short video scenario. Supported by the customer inspiration theory, this study explores the psychological mechanism underlying impulse purchase in short videos that differentiates the traditional web shopping by the strong sense of presence in short video marketing. On the basis of a questionnaire survey and three laboratory experiments, this study examines the relationship among presence, customer inspiration, and impulse purchase intention. The empirical results point to the fact that social presence, co-presence, and physical presence have significant positive effects on impulse purchase intention, and customer inspiration mediates the effect of social presence, physical presence, and co-presence on impulse purchase intention. Furthermore, it is indicated that social and co-presence have stronger influences on impulse purchase intention than physical presence, thus proving a stronger effect of social factors on impulse purchase intention than physical factors in short video environment. The research results testify the impact of presence on consumer behavior in the upgrading short video marketing and provide valuable reference for marketing strategies to shorten consumers' decision-making time in short video purchase.

NIS-Mediated Oxidative Lactonization of 2-Arylbenzoic Acids for the Synthesis of Dibenzopyranones under Metal-Free Conditions

Synthesis (2013)

Yunyang Wei Peng Gao

A series of dibenzopyranones were synthesized from 2-arylbenzoic acids by a radical oxidative cyclization procedure mediated by N-iodosuccinimide (NIS). The methodology is distinguished by its practicality in terms of its wide substrate scope, good functional group tolerance, and mild reaction conditions without the use of transition metals.

Efficient oxidative cyclization of N-acylhydrazones for the synthesis of 2,5-disubstituted 1,3,4-oxadiazoles using t-BuOI under neutral conditions

Heterocyclic Communications (2013)

Peng Gao Yunyang Wei

Abstract An efficient procedure for the oxidative cyclization of N -acylhydrazones was developed utilizing tert -butyl hypoiodite ( t -BuOI), which is generated in situ from t -BuOCl and NaI. A variety of 2,5-disubstituted 1,3,4-oxadiazoles were synthesized in high yields within short reaction time. The method is also suitable for cyclization of N -acylhydrazones derived from heterocyclic aldehydes and aliphatic aldehydes. Mild reaction conditions and simple workup operations make the procedure a good alternative for the synthesis of 2,5-disubstituted 1,3,4-oxadiazoles.
