A scalable and modular total synthesis of 3-lipid I and 3-lipid II was accomplished by a novel route involving an efficient solid phase synthesis of the peptide fragment and an effective chemoenzymatic attachment of the second sugar moiety. The generality of this route was further documented by the synthesis of an analogue bearing the pentaglycine interpeptidic bridge modification characteristic for

lipid I and II analogs is reported. The modular route was based on a three coupling strategy involving an efficient solid phase synthesis of the elaborate peptide fragment, which proceeded with excellent yield and stereoselectivity and was efficiently applied for the convergent synthesis of 3-lipid I and II. Furthermore, the generality of this route was demonstrated by synthesis of 3-lipid I congeners
