  • Diels-Alder reaction of aldehydes with simple dienes
    申请人:QUEST INTERNATIONAL B.V.
    公开号:EP0854143A1
    公开(公告)日:1998-07-22
    The invention concerns Diels-Alder reactions between non-activated aldehydes RCHO in which R is a C1-C10 aliphatic group or phenyl group, which is unsubstituted or substituted with one or more C1-C5 alkyl groups or one other functional group, with simple aliphatic dienes R1CH=CR2-CR3=CHR4 in which R1-R4 are H or C1-C5 alkyl groups using as a catalyst a perfluorinated organic sulphonic acid or a Brönsted acid derivative thereof. The reaction leads to dihydropyrans of the structure below in which R1-R4 have the meaning indicated above. The preferred perfluorinated organic sulfonic acids are perfluorooctanesulphonic acid, triflic acid, Nafion or a Brönsted acid derivative of triflic acid. The preferred aldehydes are those wherein R is a C2-C6 aliphatic group or a phenyl group which is unsubstituted or mono-substituted with C1-C3 alkyl or with 4-Cl, 4-nitro or 3-methoxy. The preferred dienes are those wherein the groups R1-R4 are H or methyl.
    本发明涉及非活化醛 RCHO(其中 R 为未取代或被一个或多个 C1-C5 烷基或一个其它官能团取代的 C1-C10 脂肪族基团或苯基)与简单脂肪族二烯 R1CH=CR2-CR3=CHR4 (其中 R1-R4 为 H 或 C1-C5 烷基)之间的 Diels-Alder 反应,该反应使用全氟有机磺酸或其勃氏酸衍生物作为催化剂。反应生成以下结构的二氢吡喃,其中 R1-R4 具有上述含义。 优选的全氟有机磺酸是全氟辛烷磺酸、三氟丙烯磺酸、Nafion 或三氟丙烯磺酸的勃氏酸衍生物。 优选的醛是那些其中 R 为 C2-C6 脂肪族基团或苯基的醛,该基团未被 C1-C3 烷基或 4-Cl、4-硝基或 3-甲氧基取代或被 C1-C3 烷基单取代。优选的二烯烃是基团 R1-R4 为 H 或甲基的二烯烃。
