| titleOfInvention | Optically active amino acid derivatives and preparation method thereof |
| abstract | The present invention provides an optically active compound of formula 1 and a process for preparing the same:n n n <Formula 1>n n n n n n n n Wherein m is 0 or 1, R 1 is hydrogen or an amino protecting group, and R 2 together with adjacent nitrogen atoms form an aziridine or oxazolidinone ring, or is hydroxymethyl, or hydroxycarbonyl.n n n The compound of Formula 1 is an optically active compound having a dihydrofuran or a dihydropyran ring, which is introduced into the middle or the terminal of the biologically active peptide, and thus may be selectively cleaved or subsequently modified. Therefore, the compound of Formula 1 may be usefully used as an intermediate of synthetic peptides for functional proteins or functional analysis of proteins. In addition, the production method of the present invention can produce a compound of formula 1 having a stereo selectivity of 99% or more in high yield. |
