A simple asymmetric synthesis of cis-2,6-disubstituted tetrahydropyran acetic acid derivatives
摘要:
A new asymmetric synthesis of functionalised cis-2,6-disubstituted tetrahydropyran acetic acids is described. The utility of the procedure is illustrated by the synthesis of (+) and (-)-(cis-6-methyltetrahydropyran-2-yl)acetic acid, a glandular secretion of the civet cat (Viverra civetta).

against multiple human cancer cell lines. Herein, we describe an enantioselective synthesis of a desmethyl derivative and the corresponding carba-derivatives of herboxidiene. The synthesis involved Suzuki coupling of a vinyl iodide with boronate as the key reaction. For the synthesis of carba-derivatives, the corresponding optically active cyclohexane-1,3-dicarbonyl derivatives were synthesized using an
