title: Diastereoselective synthesis of all stereoisomers of beta-methoxytyrosine, a component of papuamides.
abstract: beta-Methoxytyrosine (beta-OMeTyr) is a stereoundefined component of papuamides A and B, novel cyclodepsipeptides, with anti-HIV and cytotoxic activities. For structural determination and total synthesis of papuamides, all stereoisomers of beta-OMeTyr were stereoselectively prepared from (S)- and (R)-serine, respectively.
