标 题:Formation of chiral 4-chromanones using chiral pyrrolidines in the presence of acids
发明人：MEDLOCK JONATHAN ALAN; LETINOIS ULLA; NETSCHER THOMAS; BONRATH WERNER
权利人:DSM IP ASSETS BV
摘要:The present invention relates to a synthesis of chromanones or chromanes in a stereospecific matter in view of the 2-position in the chromanone or chromane ring. It has been found that this synthesis is particularly possible in the presence of a chiral compound of a specific type and of at least one Bransted acid or in the presence a specific chiral compound having a Bransted acid functional group in the molecule.

标题 :Method of making teprenone
发明人：SAUCY GABRIEL G
摘要:The invention is directed to an efficient and economical method of making teprenone. Teprenone is synthesized by converting geranylgeraniol to teprenone by a novel route. The method of synthesis can begin with geranylgeraniol obtained from a biological source such as fermentation of a microorganism capable of producing geranylgeranyl or enzymatic synthesis in a cell free system to produce predominantly the 5E isomer of teprenone. The chemical synthesis proceeds with retention of configuration such that the teprenone produced has the isomeric configuration of the geranylgeraniol starting material.
