An efficient route to substituted N-fused aromaticheterocycles, including indolizines, imidazo[1,2-a]pyridines, and imidazo[1,5-a]pyridines from azole aldehydes, is reported. Wittig olefination of the aldehydes with fumaronitrile and triethylphosphine affords predominantly E-alkenes that undergo rapid cyclization upon treatment with a mild base. Substituent control of the 1-, 2-, and 3-positions of
报道了从唑醛制备取代的N-稠合芳香杂环的有效途径,包括中氮茚、咪唑并[1,2- a ]吡啶和咪唑并[1,5- a ]吡啶。醛与富马腈和三乙基膦的维蒂希烯化主要提供E-烯烃,其在用弱碱处理后经历快速环化。显示了所得杂芳族双环的 1-、2-和 3-位的取代基控制。或者,可分离的E-烯烃用亲电子试剂进行选择性烷基化,然后原位环化成在6-位额外取代的中氮茚。

The present invention is directed to a method for the synthesis of a bi-functional complex comprising a molecule part and an identifier oligonucleotide part identifying the molecule part. A part of the synthesis method according to the present invention is preferably conducted in one or more organic solvents when a nascent bi-functional complex comprising an optionally protected tag or oligonucleotide identifier is linked to a solid support, and another part of the synthesis method is preferably conducted under conditions suitable for enzymatic addition of an oligonucleotide tag to a nascent bi-functional complex in solution.

The present disclosure relates in part to extracts of cranberry (
Vaccinium macrocarpon
) comprising an enriched amount of certain compounds having anti-infective activity, e.g. antibacterial and/or antifungal activity, e.g. activity against
C. albicans
. Another aspect of the disclosure relates to combined cranberry and cinnamon extracts. In certain embodiments, these combined extracts have been optimized to control urinary tract infections caused by
E. coli, S. aureus
and
C. albicans
. Certain embodiments of the extract are enriched in bioactive compounds that have been shown to inhibit
C. albicans
adhesion and/or biofilm formation and its growth in vitro. In another aspect of the disclosure, the extracts are enriched in bioactives derived from cranberry and cinnamon that have been shown to inhibit the attachment and the growth of common urinary tract pathogens like
E. coli, S. aureus
and
C. albicans.
