An efficient synthetic method of 1,4-dihydronaphthalenes having various alkyl groups on the 4-position and/or ethoxycarbonyl group on the 2-position through selective intramolecular Pt-catalyzed 6-endo cyclohydroarylation of ethyl 2-benzyl-2,3-alkadienoates was developed. The present method could be further extended to two-fold Pt-catalyzed 6-endo and 7-endo cyclizations.
的具有通过选择性上的2-位上的4位和/或乙氧羰基的各种烷基分子内的Pt催化的6- 1,4-二氢萘的高效合成法内的2-苄基-2,3- alkadienoates的cyclohydroarylation发展了。本发明的方法可进一步扩展到两倍的Pt催化6-内切和7-内的环化反应。
