This invention resides in a hitherto unknown class of chemical compounds, 2H-furo[2,3-c]pyran-2-ones including derivatives and analogues thereof. It includes methods for making compounds within said class and includes, without limitation, at least the intermediates employed in the generation of said compounds. The invention also relates to the use of vinylogous 4H-pyrones, including but not limited to the hitherto unknown 2H-furo[2,3-c]pyran-2-ones. In one aspect the invention resides in a method comprising the step of: exposing biological plant material to at least a compound of the invention to promoting bioactivity within said material. In another aspect the invention resides in methods for promoting growth of plant material in, for example, smoke-responsive plant species by exposing said material to a compound of the invention. More specifically, the invention relates to the use of said compounds for promoting seed germination of a plant, for example, a smoke-responsive plant.
该发明涉及一类迄今未知的化合物,2H-呋喃[2,3-c]吡喃-2-酮及其衍生物和类似物。它包括制备该类化合物的方法,并包括至少用于生成该类化合物的中间体,但不限于此。该发明还涉及使用乙烯基4H-吡喃,包括但不限于迄今未知的2H-呋喃[2,3-c]吡喃-2-酮。在一方面,该发明涉及一种方法,包括步骤:将生物植物材料暴露于发明中的至少一种化合物中,以促进该材料内的生物活性。在另一方面,该发明涉及通过将该材料暴露于发明中的一种化合物中,来促进例如对烟雾敏感的植物物种中的植物材料的生长的方法。更具体地说,该发明涉及使用该类化合物促进植物的种子萌发,例如对烟雾敏感的植物。
