多环化合物的合成。第八部分 Friedel-Crafts用三羧酸的酸酐酰化。16,17-二氢-17-甲基-15 H-环戊[ a ]菲的合成
摘要:
描述了萘,1-和2-甲基萘以及1,2,3,4-四氢萘与丙烷-1,2,3-三羧酸1,2-酐及其2-甲基衍生物的酰化作用。通过这种方法已经以高收率制备了1,2,3,4-四氢-氧杂菲乙酸。中间体的结构是通过独立合成建立的。通过萘与3-甲基丁烷-1,2,4-三羧酸1,2-酐的酰化反应生成的酮酸已被用于一种新的,改进的生产16,17-二氢-17-甲基-15 H-的途径。环戊[ a ]菲(Diels烃)。由萘和2-甲基丙烷-1,2,3-三羧酸的酮酸-1,2-酐转化成外消旋的雌-1,3,5(10),6,8-五烯-17-酮[反式-(±)-3-deoxyequilenin]通过已知方法。
The present invention comprises small molecular weight, non-peptidic inhibitors of formula I and II of Protein Tyrosine Phosphatase 1 (PTP1) which are useful for the treatment and/or prevention of Non-Insulin Dependent Diabetes Mellitus (NIDDM).

Non-peptide antagonists of the peptide hormone oxytocin (OT) with nanomolar OT receptor affinities are described. These compounds incorporate novel amido- and amidoalkylcamphor variations to the lead structure L-366,509 (1) to achieve receptor affinity enhancements of 2-3 orders of magnitude over that compound. The new OT antagonist L-367,773 (35) is shown to be an orally bioavailable agent with good

A resin is provided which is the adduct of a monocarboxylic acid and a diglycidyl ether of a bisphenol or of a monocarboxylic acid, a bisphenol and a diglycidyl ether of a bisphenol, reacted with an anhydride to an Acid No. of 35 to 150. This resin is solubilized with a volatile amine, ammonia or NH4OH in a solvent mixture of water, alkoxyethanols, alcohols and alkyl ethers of diethylene glycol and combined with an aminoplast to produce a coating composition utilizable to coat surfaces that will contact a food or beverage, such as in metal packaging containers.
