STRATEGY IN ORGANIC SYNTHESIS

In this paper, several designs and the concepts in syntheses of natural products performed in our laboratory are described. 1) Syntheses of cat attractants under thermodynamically controlled conditions; 2) Synthesis of verbenalin, an iridoid glycoside, under kinetically controlled conditions; 3) Preparations of bioactive substances by oxidative degradation of carotenoids, as an example of interpretation and utilization of abnormal reactions; 4) Syntheses of ketones based on mimic enzymatic reactions.
