[reaction: see text] A chiral indium complex has been discovered to effect high enantioselectivities in the addition of allyltributylstannanes to ketones. The allylation of a variety of aromatic, alpha,beta-unsaturated and aliphatic ketones resulted in good yields and high enantioselectivities (up to 92% ee).

Due to a rapid growth in the air transport industry, ASEAN (Association of Southeast Asia Nations) region has experienced a surge in the air traffic movement in recent years. Several forecasting papers foretell to have the continuous traffic growth for ASEAN region [1, 2]. The pilot study of ATS routes forecasts also conclude that there is a need to relook at the current route structures in selected areas in ASEAN [3]. The interaction between the structure of ATS routes and the number of intersections has been studied by using the number of conflicts [4]. This paper will serve as a continuation of the previous study, and the objective is to determine whether there is any consistency in the conclusion when the selected area is changed, using the methodology proposed.

Alcohols Q 0230Catalytic Enantioselective Allylation of Ketones via a Chiral Indium(III) Complex. -The first highly catalytic enantioselective allylation of ketones using a chiral indium(III) complex prepared from (R)-BINOL and InBr3 is described. The corresponding alcohols are prepared in good yields and enantioselectivity. The chiral ligand can be recovered in high yield. -(TEO, Y.-C.; GOH, J.-D.; LOH*, T.-P.; Org.
