  3-(3-Methyl-4-hydroxyphenyl)-3-methylbutyl aldehyde may be produced from 3-(3-methyl-4-hydroxyphenyl)-3-methylbutyric acid by converting the carboxyl group into a formyl group. N-[N-[3-(3-methyl-4-hydroxyphenyl)-3-methylbutyl]-L-&agr;-aspartyl]-L-phenylalanine 1-methyl ester, which is useful as a sweetener having a high potency of sweetness, can be easily and efficiently prepared on an industrial production from such an aldehyde derivative, via a reductive alkylation reaction with aspartame. Therefore, 3-(3-Methyl-4-hydroxyphenyl)-3-methylbutyl aldehyde is extremely excellent as an intermediate for the production of N-[N-[3-(3-methyl-4-hydroxyphenyl)-3- methylbutyl]-L-&agr;-aspartyl]-L-phenylalanine 1-methyl ester. The above butyric acid derivative is a novel compound, which can be easily produced by subjecting 3-(3-methyl-4-methoxyphenyl)-3-methylbutyric acid obtained by the reaction of 2-methoxytoluene with 3-methylcrotonic acid, to a reaction for converting a methoxy group into a hydroxyl group. The present invention further provides several novel compounds useful as a production intermediate, such as the above aldehyde derivative and the like.

  3-(3-甲基-4-羟基苯基)-3-甲基丁醛可以通过将羧基转化为甲醛基而从3-(3-甲基-4-羟基苯基)-3-甲基丁酸中产生。N-[N-[3-(3-甲基-4-羟基苯基)-3-甲基丁基]-L-α-天冬氨酸]-L-苯丙氨酸1-甲基酯是一种高甜度的甜味剂，可以通过与阿斯巴甜进行还原烷基化反应，从这种醛衍生物中轻松高效地制备出来，因此3-(3-甲基-4-羟基苯基)-3-甲基丁醛作为N-[N-[3-(3-甲基-4-羟基苯基)-3-甲基丁基]-L-α-天冬氨酸]-L-苯丙氨酸1-甲基酯的生产中间体非常出色。上述丁酸衍生物是一种新颖化合物，可以通过将2-甲氧基甲苯与3-甲基巴豆酸反应得到的3-(3-甲基-4-甲氧基苯基)-3-甲基丁酸经过将甲氧基转化为羟基的反应而轻松制备。本发明还提供了几种新颖的化合物，如上述醛衍生物等，用作生产中间体。
