A novel parallel medicinal chemistry (PMC)-enabled synthesis of 1H-pyrazolo[3,4-d]pyrimidines employing condensation of easily accessible N-pyrazolylamides and nitriles has been developed. The presented studies describe singleton and library enablements that allowed rapid generation of molecular diversity to examine C4 and C6 vectors. This chemistry enabled access to challenging alkyl substituents
已开发出一种新颖的平行药物化学(PMC)合成1 H-吡唑并[3,4- d ]嘧啶的方法,该方法采用易于获得的N-吡唑烷基酰胺和腈的缩合反应。提出的研究描述了单例和库使能,其允许快速产生分子多样性来检查C4和C6载体。这种化学性质使人们能够使用具有挑战性的烷基取代基,从而扩大了整个化学空间,使其超过了典型的C(sp 2)–C(sp 2)偶联和S N Ar转化所能提供的空间。此外,讨论了允许使用更大和更多样化的酰胺和羧酸作为腈前体的单体基团互变。

Alkylcarboxamides can be converted to the respective amines by Hofmann rearrangement using hypervalent iodine species generated in situ from PhI and Oxone in aqueous acetonitrile. On the basis of this reaction, a convenient experimental procedure for the preparation of alkylcarbamates using Oxone as the oxidant in the presence of iodobenzene in methanol has been developed. An efficient method for direct

A three-component, titanium-mediated synthesis of α-branched N-acylamines from commercial or readily accessible amides, aldehydes, and organometallic reagents is reported. The transformation proceeds under mild reaction conditions and tolerates a variety of functional groups (including nitrile, carbamate, olefin, basic amine, furan, and other sensitive heteroaromatics) to generate a large umbrella
