a 3-alkyl resorcinol derivative (3) precedes alkylation was applied in the synthesis of chiloglottone 1 (1dc), in 58% overall yield. Chiloglottone 1 is a member of a new class of natural products, representing a known sex pheromone of the thynnine wasp Neozeleboria cryptoides and pollinator attractant in the Australian sexually deceptive orchid genus Chiloglottis. The synthetic homologues were assessed
通过一个顺序描述了单烷基和2,5-二烷基-1,3-环己二酮(1)的五步合成过程,该过程涉及从容易获得且廉价的起始原料进行连续的桦木还原和烷基化,3,5-二甲氧基苯甲酸。考虑了两种方法,其中在C-2处的烷基化发生在所提出的还原之前或之后。一种成功的方法,其中3-烷基间苯二酚衍生物(3)的桦木还原在烷基化之前进行,已成功用于合成Chiloglottone 1(1dc),总收率为58%。Chiloglottone 1是一类新的天然产物的成员,代表了澳大利亚性欺骗性兰花属Chiloglottis中的一种已知的胸腺黄蜂新性紫斑狼疮性信息素和传粉媒介引诱剂。通过电造影检查评估合成的同系物的生物活性。
