Amino Acids and Peptides. XX. Preparation of .BETA.-Cyclododecyl Aspartate and Its Application to Synthesis of Fibronectin- and Laminin-Related Peptides.
beta-Cyclododecyl aspartate was prepared and its application to peptidesynthesis was examined. Derivatives of beta-cyclododecyl aspartate are more likely to crystallize and should be useful for peptidesynthesis. The cyclododecyl ester was much stable to bases than the benzyl ester and rather more stable than the cyclohexyl ester. It was removable by HF treatment and trifluoromethanesulfonic acid treatment
