手性相转移催化剂的合成及其不对称诱导效应Ⅰ——(1S,2R)-(一)-(1-对硝基苯基-1,3-二羟基-2-丙基)三甲基碘化铵
Synthesis and asymmetric Induction of chiral phase transfer catalysts 1--(1S,2R)-(-)-(1-paranitrophenyl-1,3-dihydrox-yl-2-propyl) trimethylammonium iodide
【摘要】 以氯霉素为原料,经水解、叔胺化、季铵化合成了光学纯(1S,2R)-(-)-(1-对硝基苯基-1,3-二羟基-2-丙基)三甲基 碘化铵,作为相转移催化剂,它对苯乙腈的α-甲基化、苯甲醛与氯仿的亲核加成均显示良好的催化作用和一定的不对称 诱导效应。
【Abstract】 (1S, 2R)-(-)-(1-Para-nitrophenyl-1,3-dihydroxyl-2-propyl) trimethylammonium iodide was synthesized through hydrolysis, tert-aminolation and quaterization by beginning with chioramphenicol, and as a phase transfer catalyst, it shows good catalytic and certain asymmetric induction effect in a-methylation of phenylacetonitrile, and in addition of benzaldehyde with chloroform.
