Rearrangement of β-tertbutyldimethylsiloxy carbenoids. Regio- and stereoselective synthesis of (Z)-1-Halo-2-tert-butyldimethylsiloxy-1-alkenes
摘要:
Treatment of an ether solution of 1,1-dihalo-2-tert-butyldimethylsiloxyalkane 1 with lithium diisopropylamide at 78-degrees-C gave lithium carbenoid 2 which provided (Z)-1-halo-2-tert-butyldimethylsiloxy-1-alkene regio- and stereoselectively upon warming to room temperature.
