A novel process for the preparation of sulfonic acid esters containing a lactonic ring comprising compounds in the trans form in the 4- and 5-positions having (4SR,5RS), (4S,5R) or (4R,5S) configuration of the formula ##STR1## wherein Z is selected from the group consisting of alkyl of 1 to 4 carbon atoms and cycloalkyl and monocyclic aryl optionally substituted with at least one member of the group consisting of alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms, halogen and nitro and R is organic residue of an optionally chiral alcohol of the formula ROH and a process using the compounds of formula I to prepare compounds of (1RS, 4RS, 5SR), (1S, 4S, 5R) or (1R, 4R, 5S) configuration of the formula ##STR2## wherein X is selected from the group consisting of hydrogen and R useful for the preparation of insecticidally active esters.
一种用于制备含有内酯环的磺酸酯的新工艺,包括处于4-和5-位置的具有(4SR,5RS)、(4S,5R)或(4R,5S)构型的反式化合物,其化学式为:其中Z选自由1至4个碳原子的烷基、环烷基和单环芳基,可选择地取代至少一种由1至4个碳原子的烷基、1至4个碳原子的烷氧基、卤素和硝基组成的基团,R是化学式为ROH的可选择手性醇的有机残基,以及使用化合物I的工艺来制备具有(1RS,4RS,5SR)、(1S,4S,5R)或(1R,4R,5S)构型的化合物的工艺,其化学式为:其中X选自氢和R的群,用于制备具有杀虫活性酯的化合物。
