The first organocatalytic enantioselective intramolecular 1,5-hydride transfer/ring closure reaction is described. This redox neutral reaction cascade allows for the efficient formation of ring-fused tetrahydroquinolines in high enantioselectivities.

The objective of this paper is to underline the factors influencing the implementation of integrated project delivery (IPD) in public sector construction projects. These factors are broadly classified under legal, organizational and technological categories. Further the role of information modeling to foster the integration in project delivery is discussed. Focus is placed on the aspects/characteristics of information modeling that can contribute to implementation of integrated project delivery. Traditional project delivery methods have been found by researchers as inefficient and litigious. As a result, the construction industry is in a critical need of alternative delivery methods.IPD has emerged as a solution, although its implementation is not without challenges. Therefore factors influencing its implementation should be identified as a step towards its probable use in the future for public-sector construction projects. Owners, particularly the public ones, are apprehensive due to various factors. The purpose of this paper is to investigate these factors and suggest an information modeling approach to overcome the impediments.
