摘要:借助手性磷酸和二氰基吡嗪衍生的生色团(dpz)光敏剂的双重有机催化体系,并在可见光照射下,将α-氨基酸衍生的氧化还原活性酯(rae)的对映选择性minisci型加到异喹啉中已经被开发出来.从rae产生的各种前手性α-氨基烷基已成功引入异喹啉,以高收率提供了一系列有价值的α-异喹啉取代的手性仲胺,具有非常好或优异的对映选择性.

标 题 :α-chlorinated carbonates, their method of manufacture and application in the protection of the amine functions of amino acids

权利人:POUDRES & EXPLOSIFS STE NALE
摘要:The invention relates to carbonates of formula: ##STR1## in which X is a fluorine, chlorine or bromine atom and R 1 is different from the ##STR2## group and represents: a substituted or non-substituted, saturated or unsaturated, aliphatic, araliphatic, primary, secondary, tertiary or cycloaliphatic radical. These α-chlorinated carbonates are prepared by the action of a compound of formula R 1 OH on a chloroformate of formula: ##STR3## in a solvent medium in the presence of an acid scavenger which is added after the two preceding compounds. They are used to block the amine function of amino acids. The α-chlorinated carbonate and amino acid are reacted in a solvent medium at a temperature of -5° to 100° C. in the presence of an acid scavenger. Blocked amines are very useful in peptide synthesis.
