Aldo! Condensation of Butanone with Various Aldehydes

open access: yesNippon kagaku zassi, 1968
ブタノンと種々のアルデヒドのアルカリ触媒アルドール縮合においては, アルデヒドのカルポニル基がケトンのメチレン基またはメチル基と縮合していわゆるイソ体またはノルマル体を生ずるが, この場合反応条件が異性体の生成比率にいかに影響するかをガスクロマトグラフィーを用いて研究した。iso/n の比率は一部は反応条件により, 一部は反応するアルデヒドの構造により支配された。メタノール性水酸化カリウムによるシトロネラールとの縮合では, 共役不飽和ケトンのほかいわゆるメトキシ体 (7,11-ジメチル-5-メトキシ-10-ドデセン-3-オン)を生じたので, この種のアルコキシ体を生ずべき条件も検討した。異性体比率は α,β -不飽和アルデヒドの場合強く反応条件の影響を受けたので ...
