  The attempted first stereoselective synthesis of 2,2'-biindoline using a metathesis-Sharpless asymmetric dihydroxylation strategy results in the synthesis of the heterocycle in poor to modest stereoselectivity. Attempts to improve the ee by varying the heteroatom protecting groups in key intermediates did not enhance the outcome of the Sharpless AD reaction. Therefore a limitation of this AD reaction is the use of 1,4-substituted but-2-enes where these substituents are ortho-substituted aromatics. Crown Copyright (C) 2010 Published by Elsevier Ltd.

  The invention relates to a method of forming an olefin from a first olefin and a second olefin in a metathesis reaction, comprising step (i): (i) reacting the first olefin with the second olefin in the presence of a compound that catalyzes said metathesis reaction such that the molar ratio of said compound to the first or the second olefin is from 1 : 500 or less, and the conversion of the first or the second olefin to said olefin is at least 50 %, characterized in that as compound that catalyzes said metathesis reaction a compound of formula (A) is used: wherein M is Mo or W; R1 is aryl, heteroaryl, alkyl, or heteroalkyl; optionally substituted; R2 and R3 can be the same or different and are hydrogen, alkyl, alkenyl, heteroalkyl, heteroalkenyl, aryl, or heteroaryl; optionally substituted; R5 is alkyl, alkoxy, heteroalkyl, aryl, heteroaryl, silylalkyl, silyloxy, optionally substituted; and R4 is a residue R6-X-, wherein X = O and R6 is aryl, optionally substituted; or X = S and R6 is aryl, optionally substituted; or X = O and R6 is (R7, R8, R9)Si; wherein R7, R8, R9 are alkyl or phenyl, optionally substituted; or X = O and R6 is (R10, R11, R12)C, wherein R10, R11, R12 are independently selected from phenyl, alkyl; optionally substituted; and to the catalysts used in the method.
