Catalytic Enantioselective Pictet–Spengler Reaction of α‐Ketoamides Catalyzed by a Single H‐Bond Donor Organocatalyst

Jieping Zhu, Qiang Wang, Rémi Julien Sylvain Andres

The asymmetric Pictet–Spengler reaction (PSR) with aldehydes is well known. However, PSR involving ketones as electrophilic partners is far-less developed. We report herein the first examples of catalytic enantioselective PSR of tryptamines with α-ketoamid ...

Taming the radical cation intermediate enabled one-step access to structurally diverse lignans

Jieping Zhu, Cédric Fung, Qiang Wang, Jia-Chen Xiang

Lignans, in spite of their structural diversity, are all biosynthetically derived from coniferyl alcohol. We report herein a divergent synthesis of lignans from biomass-derived monolignols in a short synthetic sequence. Blue LED irradiation of a dichlorome ...

Copper‐Catalyzed Aza‐Sonogashira Cross‐Coupling to Ynimines: Development and Application to the Synthesis of Heterocycles

Jieping Zhu, Qiang Wang, Rémi Hugo Lavernhe

Nitrogen substituted alkynes such as ynamines and ynamides are versatile synthetic building blocks in organic chemistry. Ynimines bearing additional nucleophilic and electrophilic centers relative to ynamines and ynamides are expected to have high syntheti ...

Algorithmic Verification of Component-based Systems

Qiang Wang

This dissertation discusses algorithmic verification techniques for concurrent component-based systems modeled in the Behavior-Interaction-Priority (BIP) framework with both bounded and unbounded concurrency. BIP is a component framework for mixed software ...

Parameterized Systems in BIP: Design and Model Checking

Joseph Sifakis, Simon Bliudze, Qiang Wang

BIP is a component-based framework for system design that has important industrial applications. BIP is built on three pillars: behavior, interaction, and priority. In this paper, we introduce first-order interaction logic (FOIL) that extends BIP to system ...

Automatic Fault Localization for BIP

Simon Bliudze, Qiang Wang

This paper presents a novel idea of automatic fault localization by exploiting counterexamples generated by a model checker. The key insight is that, if a candidate statement is faulty, it is possible to modify (i.e. correct) this statement so that the cou ...

Verification of Component-based Systems via Predicate Abstraction and Simultaneous Set Reduction

Simon Bliudze, Qiang Wang

This paper presents a novel safety property verification approach for component-based systems modelled in BIP (Behaviour, Interaction and Priority), encompassing multiparty synchronisation with data transfer and priority. Our contributions consist of: (1 ...

SeBip: a symbolic executor for BIP

Simon Bliudze, Qiang Wang

This paper presents SeBip, the first symbolic executor for component-based systems modelled in BIP (Be- haviour, Interaction and Priority). To tackle the path explosion problem, SeBip combines partial order reduction technique to reduce the number of inter ...

TOA: a tag-owner-assisting RFID authentication protocol toward access control and ownership transfer

Chao Wang, Qiang Wang, Chen Zhang, Lei Xie

This paper addresses radio frequency identification (RFID) authentication and ownership transfer in offline scenarios. Four typical related works are reviewed in detail. A series of shortcomings and vulnerabilities of them are pointed out. A new RFID authe ...
