The Total synthesis of (+)-artemisinin and (+)-9-desmethyltemesinin

Abstract (+)-Artemisinin has been synthesized from the 3R -methylcyclohexanone 4 in 12 steps.

Synthesis of ketomethylene analogs of dipeptides

Abstract A convenient method of synthesizing ketomethylene dipeptides by using homoallylic Grignard reagents as amino acid analog synthons is described.

Stereocontrolled synthesis of (2S,3S,8S,9S,4E,6E)-3-amino-9-methoxy-2,6,8-trimethyl-10-phenyldeca-4,6-dienoic acid (Adda), the amino acid characteristic of microcystins and nodularin

(4R,5S)-4-Methyl-5-phenyloxazolindin-2-one has been used as a chiral template to construct the 8S and 9S chiral centres of (2S,3S,8S,9S)-3-amino-9-methoxy-2,6,8-trimethyl-10-phenyldeca-4,6-dienoic acid (Adda), the 2S and 3S centres being derived from D-aspartic acid.
