  摘要：

  β-羟基酮的不稳定酯的水解已用各种蔬菜的整个植物组织进行。信息素 5-羟基-4-甲基-3-庚酮 (1) 用作模型化合物。使用正常的酯水解条件，无论是通过化学水解还是通过商业脂肪酶，1的乙酸酯和苯甲酸酯的水解均不成功。然而，当使用胡萝卜、芹菜根、茄子、欧芹根、防风草和马铃薯的全细胞作为试剂时，乙酸盐的水解是成功的。在低转化率下，水解是立体选择性的，并且在完全转化率下，几乎没有观察到副产物的形成。所评估的八种蔬菜的选择性各不相同。检查了制备方法和基质与植物的比例。此外，三种类似化合物的乙酸酯和苯甲酸酯[5-羟基-3-庚酮(2)、5-羟基-5-甲基-3-庚酮(3)和5-乙基-6-羟基-4-辛酮(4) ]被马铃薯和甘薯不同程度地水解，表明该方法对于仲β-烷氧基酮和β-芳氧基酮的温和立体选择性水解具有通用性。

  representative series of aldehydes, both of differing steric requirements provides aldols whose enantiomeric purities depend on the steric requirements of both the ketones and the aldehydes. This study has shown that increasing the steric requirements of the R group in the ketones has a pernicious effect on the ee, while increasing the steric requirements of the R group in the aldehydes exerts a beneficial

  Hydrolysis of labile esters of β-hydroxyketones has been performed with whole plant tissue from various vegetables. The pheromone 5-hydroxy-4-methyl-3-heptanone (1) was used as the model compound. Hydrolysis of acetates and benzoates of 1 was unsuccessful using normal conditions of ester hydrolysis, both by chemical hydrolysis and by the means of commercial lipases. When, however, whole cells of carrot, celery root, eggplant, parsley root, parsnip and potato were used as reagents, hydrolysis of the acetates was successful. At low conversion the hydrolysis was stereoselective and at total conversion virtually no formation of by-products was observed. The selectivity varied among the eight vegetables that were evaluated. Methods of preparation and substrate-to-plant ratio were examined. Furthermore, acetates and benzoates of three analogous compounds [5-hydroxy-3-heptanone (2), 5-hydroxy-5-methyl-3-heptanone (3) and 5-ethyl-6-hydroxy-4-octanone (4)] were hydrolyzed by potato and sweet potato to various degrees, indicating that the method is general for the mild and stereoselective hydrolysis of secondary β-alkoxy- and β-aryloxyketones.
