convenient route for the synthesis of an unsaturated branched sugar bearing a carboxylic acid and an amino group (masked as an azide group) by employing a totally stereoselective Claisen−Johnson rearrangement as the key step. Several Met- and Leu-enkephalin analogues with different substitution patterns at the N- and C-termini were prepared by incorporating this sugar amino acid (SAA) as a substitute
An endermic liniment containing at least one type of phenylalanine derivative and/or its salt. This endermic liniment has a melanin production suppression effect and is superior in terms of its skin whitening effect such as preventing and/or improving chloasma, freckles and pigmentation in the skin after sunburn, and it is also stable and highly safe. The endermic liniment containing the phenylalanine derivatives and their salts is a new, stable and highly safe endermic liniment which has a melanin production suppression effect and is superior in terms of its skin whitening effect such as preventing and/or improving chloasma, freckles and pigmentation in the skin after sunburn.
