报道了细菌信号分子环二磷酸鸟苷(c-di-GMP)的中性硫脲、尿素和碳二亚胺类似物沿着两种胍类似物的首次合成。关键中间体3′-氨基-5 ′-叠氮基-3 ′,5 ′-双脱氧衍生物经9步反应得到。5′-叠氮化物用作掩蔽的胺,通过施陶丁格还原从中获得胺,而3′-胺转化为异硫氰酸酯,其虽然对色谱和施陶丁格条件稳定,但与5′-胺反应良好。
The first syntheses of neutral thiourea, urea, and carbodiimide analogs, along with two guanidinium analogs, of the bacterial signaling molecule cyclic diguanosine monophosphate (c-di-GMP) are reported. The key intermediate, obtained in nine steps, is a 3′-amino-5′-azido-3′,5′-dideoxy derivative. The 5′-azide serves as a masked amine from which the amine is obtained by Staudinger reduction, while the 3′-amine is converted to an isothiocyanate that, while stable to chromatography, and Staudinger conditions, nevertheless reacts well with the 5′-amine.
