摘要:The invention relates to a new enantioselective synthesis for the preparation of optically active 14-oxo-E-homo-eburnane derivatives of the formula (Ia) ##STR1## wherein R 1 is alkyl having from 1 to 4 carbon atom. In the synthesis optically active 6-alkoxycarbonylhexahydroindoloquinolizinium salts are employed as starting materials, which contain a center of chirality at the site of attachment of the carboxyl group. This center of chirality preserves the optical activity of the optically active tryptophan ester from which this compound has been prepared until a new center of chirality is formed in the molecule in a configuration corresponding to the desired end product. The carboxyl group, which is not needed in the end product and only serves to preserving the optical activity can then be eliminated. n Compounds of the formula (Ia) are known in the art and may be used in the synthesis of (+)-vincamine and (+)-apovincaminic acid ethylester.

摘要:Disclosed are methods and systems for forming a silicon-containing layer on a substrate. Further disclosed are composition and synthesis of silicon-containing precursor. The methods for forming a silicon-containing layer comprise executing a plurality of deposition cycles. A deposition cycle comprises a first precursor pulse that comprises exposing the substrate to a first precursor. The first precursor comprises a molecule comprising a P—Si bond. A deposition cycle further comprises a plasma pulse that comprises exposing the substrate to a plasma treatment. The plasma treatment comprises generating a plasma.
