An efficient lactamization of fimbrolides to novel 1,5-dihydropyrrol-2-ones
摘要:
A new versatile method for the conversion of fimbrolides to the corresponding novel dihydropyrrol-2-ones is described. This new efficient lactamization protocol has the advantage of higher yields and can be used for the synthesis of a series of new dihydropyrrol-2-ones with interesting anti-bacterial properties.

Novel synthesis methods, to the products of such novel methods, and to uses of these products. In particular, the present invention provides methods for the reactions of furanones, in particular fimbrolides, with amines. The invention has particular application in the synthesis of halogenated 1,5-dihydro-pyrrol-2-one, 5-halomethylene substituted 1,5-dihydropyrrol-2-ones (lactam analogues of fimbrolides), 5-amino substituted furanones and 5-aminomethylene-2(5H)-furanones and their synthetic analogues. The invention also relates to novel compounds and uses thereof.
