Me groups adjacent to an olefinic double bond were metalated by KOCMe3 and BuLi without cis-trans isomerization. Thus, (E)-MeCH:-CHMe was metalated to give (E)-MeCH:CHCH2K (I) which reacted with ethylene oxide to give 41% (E)-MeCH:CH(CH2)3OH. If I was allo ...
During deamination, γ-amino acids can undergo concomitant decarboxylation. Aiming at studying the course of the involved reaction, the following γ-amino acids were synthesized and characterized: (–)-3c-amino-1,2,2-trimethylcyclopentane-1r-carboxylic acid ( ...
7-Halo-7-methylnorcaranes (I) and 7,7-dimethylnorcarane (II) are formed via replacement of halogen by Me during the reaction of cyclohexene (III) with carbenes (carbenoids) and MeLi. Thus, III is treated with CHClF2 or CCl2F2 and MeLi to give a mixt. of 7- ...
Reaction of cis- and trans-PhCH:CHF with RLi (R = Bu, Me, Ph, or PhCH2) gave stereoselectively cis- and trans-PhCH:CHR, with retention of configuration by substitution and PhC.tplbond.CH by elimination reaction. The elimination reaction follows mainly the ...
The syn-anti ratio of 7-(R-substituted)-norcaranes (I, R = Ph. F, Cl) formed in the cycloaddn. of cyclohexene (II) with PhCH2F, PhCH2Cl, PhCHBrF, PhCHBr2, FCHBr2, ClCHBr2, or CH2Cl and BuLi in various solvents under N was examd. with respect to influences ...
Azides are building blocks of increasing importance in synthetic chemistry, chemical biology, and materials science. Azidobenziodoxolone (ABX, Zhdankin reagent) is a valuable azide source, but its safety profile has not been thoroughly established. Herein, ...
