Abstract
Abstract In order to find a suitable organometallic compound and a catalyst for the arylation of 8-acetoxyoctalenone 4 (a stereoisomeric mixture of 4α and 4β), phenylation was first investigated with PhZnX (7: X= Cl; 8: X= Br)/Pd or Ni cat., PhSnBu 3 (9)/Pd cat. and LiCl, and [PhB (Bu)(OCHMeCHMeO)] Li (10a)/Ni cat. Borate 10a provided the desired product 11a with high stereoselectivity. The stereochemical outcome was irrespective of the ...
