The Intramolecular Diels-Alder reactions of furans possessing a 2-alkyl substituent with a terminal α,β-unsaturated ketone have been surveyed. The consequences of varying the degree of substitution of the furan, the bridging chain length, and position of the activating group on the dienophile upon the ease and stereochemistry of cycloaddition are reported.
已经研究了具有2-烷基取代基和末端α,β-不饱和酮的呋喃的分子内Diels-Alder反应。据报道,改变环加成反应的简便性和立体化学后,改变呋喃的取代度,桥链长度以及亲二烯体上活化基团的位置的后果。
