摘要:Abstract(#br)A convenient gold-catalyzed asymmetric synthesis of polysubstituted furfurylamines starting from amino acids has been achieved. The cyclization proceeded under mild conditions and generally provided the furan or iodofuran derivatives in good to excellent yields and w...

摘要:Abstract(#br)Two types of indolizidine derivatives can be synthesized from amino-ynones. In the presence of methanesulfonic acid, Meyer–Schuster rearrangement furnished vinylogues of indolizidin-3-ones whereas treatment with zinc chloride gave stable 3-alkynyl-1,5,6,7,8,8 a ...

摘要:Abstract(#br)The solid-phase synthesis of several γ-methyl-substituted-γ-butyrolactones using a cyclisation–cleavage reaction is reported. Chemical modifications of polymer-bound azido ( 2a ) and iodo alcohols ( 2b ) were realised in order to introduce additional diversity o...

摘要:Abstract(#br)PPARγ and Nrf2 are important transcriptional factors involved in many signaling pathways, especially in the anti-infectious response of macrophages. Compounds bearing a Michael acceptor moiety are well known to activate such transcriptional factors, we thus eval...

摘要:Abstract(#br)(bda)Fe(CO) 3 and (COT)Fe(CO) 3 are shown to be excellent catalysts for the tandem isomerization–aldol reaction of allylic alcohols with aldehydes and to significantly increase the scope of this aldolization process, especially, in the case of sterically hindere...

摘要:Abstract(#br)A light-fluorous catch and release approach application has been designed to the separation of a mixture of three paraconic acids extracted from the Island moss ( Cetraria islandica (L.) Ach.). The (+)-protolichesterinic acid was caught and released via a Michaë...

摘要:Abstract(#br)Kavalactone derivatives were synthesized using a Heck reaction of the 4-methoxy-6-vinyl-5,6-dihydropyran-2-one with aryl iodides. The Suzuki–Miyaura reaction of an aryl boronic acid and ( Z )-4-methoxy-6-(2-iodovinyl)-5,6-dihydropyran-2-one has also been success...

摘要:Abstract(#br)Alkylation of secondary sulfonamides by alkyl halides or alcohols (Mitsunobu reaction) is an efficient method for secondary amines preparation. However, its application to parallel chemistry is often difficult due to partial reaction. In this Letter, we propose a flu...

摘要:Abstract(#br)Using easily accessible aromatic alkoxy-arylalkynones, we have investigated the gold-catalyzed intramolecular addition of ethers to alkynes, to give easy access to various substituted chromones. This reaction involves the transfer of the ether substituent via a carbo...

摘要:Abstract(#br)We have previously demonstrated that out of the butyrolactones series synthesized based on the natural lichen metabolite lichesterinic acid, compound ( B-13 ) was the most effective against oral bacteria. However, its antibacterial mechanism is still unknown. In this...
