  Abstract An efficient and convenient procedure has been developed for the synthesis of benzopyran derivatives by one-pot condensation of substituted salicyaldehydes and substituted 1,3-hexanediones in the presence of a catalytic amount of 2,4,6-trichloro-1,3,5-triazine (TCT, cyanuric chloride) under solvent-free conditions.

  (9S)-9-(2-Hydroxy-4,4-dimethyl-6-oxo-1-cyclohexen-1-yl)-3,3-dimethyl-2,3,4,9-tetrahydro-1H-xanthen-1-one ((S)-1) was identified as a selective and orally active neuropeptide Y Y5 receptor antagonist. The structure-activity relationship for this structural class was investigated and showed that limited substitution on the phenyl ring was tolerated and that modification of the 4,4-dimethyl group of the cyclohexenone and the 3,3-dimethyl group of the xanthenone parts slightly improved potency. The plasma concentration-time profile after oral administration of (S)-1 in Sprague-Dawley (SD) rats showed significant in vivo racemization of (S)-1 and that (S)-1 is cleared much more quickly than (R)-1. The duration of (S)-1 in SD rats after oral administration of (RS)-1 racemate was twice as long as that following oral administration of (S)-1. The Cm, values of (S)-1 after administration of (S)-1 and (RS)-1 were comparable, and the brain to plasma ratio for (S)-1 was 0.34 in SD rats. In our acute D-Trp34NPY-induced food intake model, both (S)-1 and (RS)-1 showed potent and dose-dependent efficacy. Therefore, the use of (RS)-1 is suitable for studies that require sustained plasma exposure of (S)-1.

  （9S）-9-(2-羟基-4,4-二甲基-6-氧-1-环己烯-1-基)-3,3-二甲基-2,3,4,9-四氢-1H-呫吨-1-酮 ((S)-1) 被鉴定为一种选择性且具有口服活性的神经肽Y Y5受体拮抗剂。针对这一结构类别的构效关系研究显示，苯环上的有限取代是可以耐受的，而对环己酮部分的4,4-二甲基基团和呫吨酮部分的3,3-二甲基基团进行修饰略有提高其效力。在 Sprague-Dawley (SD) 大鼠中口服给予(S)-1后，其血浆浓度-时间曲线显示(S)-1在体内发生显著的外消旋作用，并且(S)-1的清除速率远快于(R)-1。在SD大鼠中，口服给予(RS)-1外消旋体的(S)-1作用持续时间是口服给予(S)-1后作用持续时间的两倍。在(S)-1和(RS)-1给药后，(S)-1的Cmax值相当，且(S)-1在SD大鼠中的脑血浆比值为0.34。在我们的急性D-Trp3,4-神经肽Y诱导的食物摄入模型中，(S)-1和(RS)-1均显示出强大且剂量依赖性的疗效。因此，使用(RS)-1适合需要(S)-1持续血浆暴露的研究。

  A simple, experimentally rapid and efficient CsF catalyzed tandem Knoevenagel-Michael reaction protocol is developed for the synthesis of a series of functionalized 9-(2-hydroxy-4,4-dimethyl-6-oxocyclohex-1-enyl)-3,3-dimethyl-2,3,4,9-tetrahydro-1H-xanthen-1-one (1-7) by reacting dimedone with substituted salicylaldehydes. The use of CsF as a catalyst allowed reactions under moderate conditions and resulted in better yields. (C) 2013 Elsevier B.V. All rights reserved.
