摘要:This disclosure generally relates to the use of enzyme combinations or recombinant microbes comprising same to make isoprenoid precursors, isoprenoids and derivatives thereof including prenylated aromatic compounds. Novel metabolic pathways exploiting Claisen, aldol, and acyioin condensations are used instead of the natural mevalonate (MVA) pathway or 1-deoxy-d-xylulose 5-phosphate (DXP) pathways for generating isoprenoid precursors such as isopentenyl pyrophosphate (IPP), dimethylallyl pyrophosphate (DMAPP), and geranyl pyrophosphate (GPP). These pathways have the potential for better carbon and or energy efficiency than native pathways. Both decarboxylative and non-carboxylative condensations are utilized, enabling product synthesis from a number of different starting compounds. These condensation reactions serve as a platform for the synthesis of isoprenoid precursors when utilized in combination with a variety of metabolic pathways and enzymes for carbon rearrangement and the addition/removal of functional groups. Isoprenoid alcohols are key intermediary products for the production of isoprenoid precursors in these novel synthetic metabolic pathways.

标题 :Synthesis of chiral 1-benzyl-1,2,3,4-tetra-hydroisoquinolines by asymmetric reduction
发明人：RICE KENNER C
权利人:US HEALTH
摘要:In a short total synthesis of morphinan compounds, derivatives of 1-benzyl-1,2,3,4-tetrahydroisoquinoline are produced. Certain of these compounds, although highly aromatic and functionalized, can be optically resolved. The optically active enantiomers can serve as important intermediates for both natural and unnatural opioids. As a special function of this invention, certain of the derivatives, namely 4'-6' and 7'-9', may be hydrogenated to 1'-3' derivative by asymmetric reduction either of the catalytic or chemical type.
