  A compound of the formula (1) wherein R1 and R5 each represents an alkyl group having 1 to3 3 carbon atoms; R2, R3 and R4 each represents a hydrogen atom or an alkyl group having 1 to 3 carbon atoms and wherein the bonding at the 2-3 position is a single bond and that at the 3-4 position is a double when the substitution of hydroxy group is at the 5-position or the bonding at the 2-3 position is a double bond and that at the 3-4 position is a single bond when the substitution of hydroxy group is at the 7-position:; with the proviso that R2 and R4 should not be a hydrogen atom or an alkyl group simultaneously. Such a compound can be prepared by reacting resorcinol with an aliphatic ketone or a tertiary alcohol or by thermally decomposing polyalkyl (2, 4 - dihydroxyphenyl) hydroxychroman. The compound is useful as a herbicide and fungicide and as an intermediate for preparing agricultural chemicals.

  式（1）的化合物 其中 R1 和 R5 各代表一个具有 1 至 3 个碳原子的烷基；R2、R3 和 R4 各代表一个氢原子或一个具有 1 至 3 个碳原子的烷基；当羟基的取代位于 5 位时，2-3 位的键合是单键，3-4 位的键合是双键；当羟基的取代位于 7 位时，2-3 位的键合是双键，3-4 位的键合是单键：但 R2 和 R4 不能同时为氢原子或烷基。这种化合物可以通过间苯二酚与脂肪族酮或叔醇反应，或通过热分解多烷基（2，4-二羟基苯基）羟基苯并吡喃来制备。该化合物可用作除草剂和杀真菌剂，以及制备农药的中间体。
