    Patent number: 11191273
    Abstract: Disclosed herein are methods of making (4aR,6S,8aR)-6-((R)-1-hydroxyethyl)-6,8a-dihydropyrano[3,2-b]pyran-2-(4aH)-one (2) and methods of making (4aR,6S,8aR)-6-cyano-6,8a-dihydropyrano-[3,2-b]pyran-2(4aH)-one (4). Other pyranopyrans were also synthesized. Also compositions containing (4aR,6S,8aR)-6-cyano-6,8a-dihydropyrano-[3,2-b]pyran-2(4aH)-one (4) (or other pyranopyrans described herein) and optionally a carrier. In addition, methods for killing microorganisms or weeds on or in an object or area involving contacting the object or area with an effective microorganisms or weeds killing amount of a composition containing (4aR,6S,8aR)-6-cyano-6,8a-dihydropyrano-[3,2-b]pyran-2(4aH)-one (4) (or other pyranopyrans described herein) and optionally a carrier.
