A green and eco-friendly route for the almost quantitative BOC protection of a large variety of aliphatic and aromatic amines, amino acids, and amino alcohols is reported in catalyst and solvent-free media under mild reaction conditions. The products were confirmed by 1H, 13C NMR, IR spectroscopy, and in some cases, elemental analysis. This protocol does not require any water quenches, solvent separations
据报道,在温和的反应条件下,在无催化剂和无溶剂的介质中,绿色环保的路线几乎可以定量保护各种脂肪族和芳香族胺,氨基酸和氨基醇的BOC。产物通过1 H,13 C NMR,IR光谱和某些情况下的元素分析确认。该方案不需要任何水淬,溶剂分离和纯化步骤,例如重结晶和柱色谱法。
