Silylated Biphenyl Derivatives, Ethyl Benzoates, and Benzophenones by Regioselective [4 = 2]-CycloadditionsThe cycloaddition of the N-methyl-2-pyridones 1a-d with phenyl(trimethylsilyl)ethyne (2) proceeds regioselectively to give silylated biphenyl derivatives 5a, 6b, 5c, d. Similarly the reactions of ethyl (trimethylsilyl)propiolate (3) and of benzoyl(trimethylsilyl)ethyne (4) with 1a - c afford the silylated ethyl benzoates 5e, 6f, 5g and the benzophenones 5h, 6i, 5j, respectively.
Notes:
Die Cycloaddition der N-Methyl-2-pyridone 1a-d mit Phenyl(trimethylsilyl)ethin (2) verläuft regioselektiv zu den Biphenyl-Derivaten 5a, 6b, 5c, d. Entsprechend reagieren (Trimethylsilyl)-propiolsäure-ethylester (3) und Benzoyl(trimethylsilyl)ethin (4) mit 1a-c zu silylierten Benzoesäureestern 5e, 6f, 5g bzw. Benzophenonen 5h, 6i, 5j.
