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.
本发明公开了制备(4aR,6S,8aR)-6-((R)-1-羟乙基)-6,8a-二氢吡喃并[3,2-b]吡喃-2-(4aH)-酮(2)的方法以及制备(4aR,6S,8aR)-6-氰基-6,8a-二氢吡喃并[3,2-b]吡喃-2(4aH)-酮(4)的方法。还合成了其他吡喃并吡喃类化合物。还提供了含有(4aR,6S,8aR)-6-氰基-6,8a-二氢吡喃并[3,2-b]吡喃-2(4aH)-酮(4)(或本文所述的其他吡喃并吡喃类化合物)及可选载体的组合物。此外,还提供了杀灭物体或区域上或内的微生物或杂草的方法,该方法涉及将该物体或区域与含有(4aR,6S,8aR)-6-氰基-6,8a-二氢吡喃并[3,2-b]吡喃-2(4aH)-酮(4)(或本文所述的其他吡喃并吡喃类化合物)及可选载体的组合物接触,该组合物具有有效杀灭微生物或杂草的量。
