general solid phase methodology for the synthesis of depside and depsipeptide chains from optically active α-hydroxy acids and α-amino acids is reported. The automated preparation of depsides (97% yield per cycle) made up from the same enantiomer [i.e. H-[(S)-Man]8-OH, 1] † by both enantiomers [i.e. H-[(R)-Man-(S)-Man]4-OH, 2], or by different hydroxy acids in the same chain [i.e. H-[(S)-Lac-(S)-Hiv]3-OH
报道了一种由旋光性α-羟基酸和α-氨基酸合成deptide和depsepteptide链的通用固相方法。缩酚酸的自动制备(每个循环97%产率)从相同的对映体组成[即ħ - [(小号)-Man] 8 -OH,1 ] †由两种对映体[即ħ - [([R)-Man- (S)-Man] 4 -OH,2 ]或在同一肽链中的不同羟基酸[即H-[(S)-Lac-(S -Hiv)3 -OH,3 ],以及十肽交替引入α-氨基酸和α-羟基酸,例如二肽6(Cbz-[(S)-Val-(R)-Man-(R)-Val-(S)-Lac] 3 -OH)被提出。开链近端化合物的环化形成手性大环,其结构类似于冠醚的结构。
