Lewis acid-mediated ring-opening cyclization of trans- and cis-cyclopropanes 1a and 1b afforded the same trans-dihydronaphthalene 2a. Moreover, Lewis acid-mediated cyclization of 7R- and 7S-benzyloxy dibenzyl lignan lactones 5a and 5b furnished trans-tetr

Multi-substituted trans-dihydronaphthalenes were obtained in high enantiomeric excess from a TiCl4-mediated cyclization of enantioenriched donor-acceptor cyclopropanes, followed by a triflation of the hydroxy groups. The C-OTf bond in these mul
Substituent Effects in the Solvolysis of p-(2-Substituted Cyclopropyl)-α-Methylbenzyl Chlorides
Kusuyama, Yoshiaki,Kubo, Takako,Iyo, Masami,Kagosaku, Tamami,Tokami, Kenjiro
, p. 2954 - 2960 (2007/10/02)
The solvolysis rates of p-(cis- or trans-2-substituted cyclopropyl)-α-methylbenzyl chlorides including electron-donating and electron-attracting substituents relative to a hydrogen substituent were measured in 80percent aqueous acetone.The trans isomers w
