hydropyran-4-ylacetonitrile. The latter was reduced to the corresponding amine with lithium tetrahydridoaluminate, and the reduction product was brought into condensation with aromatic aldehydes. The Schiff bases thus formed were reduced with sodium tetrahydridoborate, followed by N-acylation with acetyl and propionyl chlorides.
2-异丙基四氢吡喃-4-酮[在5%硫酸和硫酸汞(II)存在下,通过3-异丙基戊-1-烯-4-炔-3-醇的异构化和水合反应]与氰基乙酸乙酯反应得到氰基(2-异丙基四氢吡喃-4-亚烷基)乙酸乙酯,将其用4-甲苯基氯化镁处理。使所得的氰基[2-异丙基-4-(4-甲苯基)四氢吡喃-4-基]乙酸乙酯去羰基乙氧基化,获得2-异丙基-4-(4-甲苯基)四氢吡喃-4-基乙腈。后者用四氢铝酸锂还原为相应的胺,并使还原产物与芳族醛缩合。这样形成的席夫碱用四氢硼酸钠还原,然后用乙酰氯和丙酰氯进行N-酰化。
