Microwave-assisted Sinthesis of Thymyl Ethers and Esters in Aqueous Medium
摘要:
Various thymyl ethers and esters have been synthesized by reactions of thymol with alkyl halides and acid chlorides, respectively, in aqueous medium under environmentally benign conditions using microwave irradiation. The products are important as potent pest managing agents.

performed using polystyrene-supported succinimidyl selenide as the selenium source. This catalytic process provides an efficient method for the regioselectivesynthesis of dihydrocoumarins possessing a seleno functionality, followed by syn elimination of selenoxides to provide coumarins in good yields and purities. Suzuki cross-coupling reaction of the resin-bound bromodihydrocoumarin was also performed

Cinnamic acid and its derivatives show a remarkable variety of biological activities and are often studied in search of the development of new and highly effective drugs. This work aims to synthesize, characterize and evaluate the cytotoxic activity of esters derived from cinnamic acid. Eighteen esters were synthesized through Steglich’s esterification, of which eleven were not reported in the literature
