Silylenamines as Synthons for Silylated HeterocyclesThe silylenamines 1a-c react with different unsaturated electrophiles to form cyclic adducts containing sulfur (2, 7, 17), oxygen (10, 14, 22), and nitrogen (19, 20, 21) in the ring. The reaction of 1a with acetylenedicarboxylate leads to the cyclobutene 8 which is opened to the pentadiene 9c, whereby the regioselectivity typical for enamines is always observed.
Notes:
Die Silylenamine 1a-c reagieren mit verschiedenen ungesättigten Elektrophilen zu cyclischen Addukten mit Schwefel (2, 4, 17), Sauerstoff (10, 14, 22) und Stickstoff (19, 20, 21) im Ring, mit Acetylendicarbonester unter Öffnung des Cyclobutens 8 zum Pentadien 9c, wobei stets die für Enamine typische Regioselektivität beobachtet wird.
