cases bearing an unsaturated tether in good yield. The resulting dienamines subsequently undergo both inter- and intramolecular [4+2] cycloaddition reactions. Good yields were obtained for a number of cases of intramolecular intermolecular cycloaddition reactions affording cycloadducts in good yields with sufficiently reactive dienophiles such as fumarate, acrylate and methacrolein. Evidence suggests

The invention provides tricyclic compounds and their use in treating medical disorders, such as obesity. Pharmaceutical compositions and methods of making various tricyclic compounds are provided. The compounds are contemplated to have activity against methionyl aminopeptidase 2.
A short and efficientsynthesis of novel tetracyclic Kynurenic acid analogues, isolatedfrom chestnut honey, is described. The crucial step of the strategy was a MW-assisted cyclization of enamines of ethyl dioxohexahydropyrrolizine and 2,3-dioxooctahydroindolizine carboxylates to obtain 2,3,6,11b-tetrahydro-1H-pyrrolizino[2,1-b]quinoline-5,11-dione and 5,8,91,011,11a-hexahydroindolizino[2,1-b]quinoline-6
描述了一种从板栗蜂蜜中分离得到的新型四环犬尿酸类似物的短而有效的合成方法。该策略的关键步骤是对二氧六氢吡咯啉乙酯和2,3-二氧八氢吲哚嗪羧酸酯的烯胺进行MW辅助环化,以获得2,3,6,11b-tetrahydro-1H-pyrrolizino [2,1- b ] quinoline-5, 11-二酮和5,8,91,011,11a-六氢吲哚并[2,1- b ]喹啉-6,12-二酮。由于其模块化性质,合成策略可以作为制备包含这些新杂环骨架的化合物的一般方法具有价值。
INTRODUCTION OF CARBON UNIT AT THE α-POSITION OF ALICYCLIC AMINES UTILIZING A DECARBOXYLATION REACTION WITH MALONIC ACID DERIVATIVES
A new method for introducing carbon unit at the α-position of alicyclic amines has been exploited. The method involves a reaction of trimers of alicyclic imines with malonic acid derivatives, of which decarboxylation leads to a formation of carbon-carbon bond at the α-position of alicyclic amines.
