[GRAPHICS]Selective N-alkylation of primary amines was developed using cesium hydroxide to prepare various secondary amines efficiently. A cesium base not only promoted monoalkylations of primary amines but also suppressed overalkylations. Various amines and alkyl bromides were examined, and the preliminary results demonstrated this methodology was highly chemoselective, favoring mono-N-alkylation over dialkylation. In particular, use of amino acid derivatives afforded the desired secondary amines exclusively.

Studies towards the synthesis of a chiralprimary α-phosphinoalkanamine 1a are reported. O-Activated. N-carbamate-protected phenylalaninol 3a did not undergo SN reaction with KPPh2: instead, after N-deprotonation, intramolecular substitution led to formation of the aziridine derivative 5a (Scheme 2). N-Phthalimido-protected, O-activated phenylalaninol 3b also underwent an intramolecular process on
报道了对手性伯α-膦烷基烷胺1a的合成的研究。O-已激活。N-氨基甲酸酯保护的苯丙氨醇3a没有与KPPh 2进行S N反应:相反,在N-去质子化之后,分子内取代导致形成氮丙啶衍生物5a(方案2)。N-邻苯二甲酰亚胺基保护的,O-激活的苯丙氨醇3b在用KPPh 2处理时也经历了分子内过程,即,这是不寻常的芳基-酰基环化反应,提供了(环氧甲氧基)异吲哚并[1,2- a ]异喹啉酮7(方案3)。与KPPh的反应2中,Ñ,Ñ二苄基保护和活化的苯丙3D最后产生的分子间小号Ñ反应产物2a中(方案4)。但是,证明不可能通过催化氢化进行脱苄基作用。
