The present invention relates to beta-amino ester compounds of active alcohols of formula:
wherein each R'1, R'2, R1, R2, independently, is selected from hydrogen, alkyl group and aryl group,
wherein each R1, R2, independently, is selected from hydrogen, alkyl group and aryl group,
wherein each n, n1, independently, is an integer lying in the range from 1 to 20, and
wherein n2 is an integer lying in the range of 1 to 6,
wherein each n3, independently, is an integer lying in the range from 1 to 3, and
wherein each R, independently, is an organic chain of an active alcohol, preferably a perfume alcohol.
The present compound is preferably used as a precursor of the corresponding betaine ester compound.
The present invention also relates to said beta-amino ester compounds of active alcohols in alkaline environment which upon and after use will allow a slow release of the active component.
本发明涉及式中活性醇的β-氨基酯化合物:
其中每个 R'1、R'2、R1、R2 独立地选自氢、烷基和芳基、
其中每个 R1、R2 独立地选自氢、烷基和芳基、
其中每个 n、n1 独立地是在 1 至 20 范围内的整数,以及
其中 n2 是 1-6 之间的整数、
其中每个 n3 独立地是在 1 至 3 范围内的整数,以及
其中每个 R 独立地是活性醇的有机链,最好是香料醇。
本发明化合物最好用作相应甜菜碱酯化合物的前体。
本发明还涉及在碱性环境中的活性醇的β-氨基酯化合物,在使用时和使用后可使活性成分缓慢释放。
