Preparation and Stereochemistry of Dioxatetraazaperhydroanthracenes and -perylenes from the Reaction of 2-Hydrazinoethanols with Aldehydes and Glutaraldehyde
Hydrazinoethanols 1 were reacted with aldehydes 2 and 6 and glutaraldehyde (14) in aqueous solution to give dioxatetraazaperhydroanthracenes 3, 7, 12, and 13 and -perylenes 15 in yields of 19-88 and 42-72%, respectively. Compounds 3, 7, 12, and 15 were deduced by (13)C-NMR spectra to have two C(2) symmetry axes, while compound 12 was shown to have a symmetry axis by X-ray crystallography. The most

In this work we describe the preparation of novel fused, spirocyclic and chiral triazolopiperazines. We have developed a practical, rapid and robust synthetic route to these scaffolds that allows control of regio- and stereochemistry. This method utilises mild conditions and uses widely available and diverse amino acids and amidines as starting materials. These complex unprecedented 5,6,7,8-tetrahydro-[1–2
在这项工作中,我们描述了新型的稠合,螺环和手性三唑并哌嗪的制备。我们已经为这些支架开发了一种实用,快速和强大的合成途径,从而可以控制区域化学和立体化学。该方法利用温和的条件,并使用广泛可用的多种氨基酸和am作为起始原料。这些复杂的史无前例的5,6,7,8-四氢-[1-2,4]三唑并[1,5- a ]吡嗪代表了药物开发的有吸引力的组成部分。
