a novel domino strategy for forming poly substituted quaternary imidazoles through a cs2co3 promoted aryl Migration Process
ChemInform, 2013Co-Authors: Wei Fan, Bo Jiang, Shuliang WangAbstract:A new and metal-free [3 + 2] heterocyclization of epoxypropanones (I) with amidines (II) gives rise to the formation of a quaternary imidazole skeleton with high regioselectivity.

a novel domino strategy for forming poly substituted quaternary imidazoles through a cs2co3 promoted aryl Migration Process
Organic and Biomolecular Chemistry, 2013Co-Authors: Wei Fan, Bo Jiang, Shuliang WangAbstract:A new domino strategy for the synthesis of highly functionalized quaternary imidazole derivatives via [3 + 2] heterocyclization, involving aryl Migration and ring-opening of oxirane, has been developed. This domino reaction enables the successful assembly of three new sigma bonds including two C–N bonds in a simple operation. Features of this strategy include the mild conditions, convenient operation, and short reaction periods (15–20 min).

a baker venkataraman retro claisen cascade delivers a novel alkyl Migration Process for the synthesis of amides
ChemInform, 2015Co-Authors: Dana Ameen, Timothy J SnapeAbstract:If water is not strictly excluded the initially formed Baker—Venkataraman rearrangement products of substrates (I) undergo retro-Claisen rearrangement to form amides (II).

a baker venkataraman retro claisen cascade delivers a novel alkyl Migration Process for the synthesis of amides
Tetrahedron Letters, 2015Co-Authors: Dana Ameen, Timothy J SnapeAbstract:Abstract A simple extension of the carbamoyl Baker–Venkataraman rearrangement has been developed. If residual water in the reaction is not strictly excluded a Baker–Venkataraman retro-Claisen cascade takes place, giving amide products, in which an alkyl group apparently migrates between two functionalities of the substrate.

Cloud Migration Process A Survey Evaluation Framework and Open Challenges
arXiv: Software Engineering, 2020Co-Authors: Fahmideh, Ghassan Beydoun, Graham Low, Farhad DaneshgarAbstract:Moving mission-oriented enterprise applications to cloud environments is a major IT strategic task and requires a systematic approach. The foci of this paper are to review and examine existing cloud Migration approaches from the Process models perspective. To this aim, an evaluation framework is proposed and used to analyse and compare existing approaches for highlighting their features, similarities, and key differences. The survey distills the state of the art in cloud Migration research and makes a rich inventory of important activities, recommendations, techniques, and concerns that are commonly involved in the Migration Process in one place. This enables academia and practitioners in the cloud computing community to get an overarching view of the cloud Migration Process. Furthermore, the survey identifies a number challenges that have not been yet addressed by existing approaches, developing opportunities for further research endeavors.

A generic cloud Migration Process model
European Journal of Information Systems, 2018Co-Authors: Fahmideh, Farhad Daneshgar, Fethi A. Rabhi, Ghassan BeydounAbstract:The cloud computing literature provides various ways to utilise cloud services, each with a different viewpoint and focus and mostly using heterogeneous technical-centric terms. This hinder...

cloud Migration Process a survey evaluation framework and open challenges
Journal of Systems and Software, 2016Co-Authors: Mahdi Fahmideh Gholami, Farhad Daneshgar, Ghassan BeydounAbstract:The relevant approaches for migrating legacy applications to the cloud are surveyed.An extensive analysis of existing approaches on the basis of a set of important criteria/features.Important cloud Migration activities, techniques, and concerns that need to be properly addressed in a typical cloud Migration Process are delineated.Existing open issues and future research opportunities on the cloud Migration research area are discussed. Moving mission-oriented enterprise software applications to cloud environments is a crucial IT task and requires a systematic approach. The foci of this paper is to provide a detailed review of extant cloud Migration approaches from the perspective of the Process model. To this aim, an evaluation framework is proposed and used to appraise and compare existing approaches for highlighting their features, similarities, and key differences. The survey distills the status quo and makes a rich inventory of important activities, recommendations, techniques, and concerns that are common in a typical cloud Migration Process in one place. This enables both academia and practitioners in the cloud computing community to get an overarching view of the Process of the legacy application Migration to the cloud. Furthermore, the survey identifies a number challenges that have not been yet addressed by existing approaches, developing opportunities for further research endeavours.
