标题 :Efficient process for the synthesis of alkoxy substituted benzaldehydes
发明人：MOHAPATRA Manoj Kumar; BENDAPUDI Ramamohanrao; MENACHERRY Paul Vincent; PAUL VINCENT
权利人:ANTHEA AROMATICS PRIVATE LTD
摘要:The present invention relates to the synthesis of alkoxy substituted benzaldehydes obtained from the corresponding alkoxy substituted benzenes. Alkoxy substituted benzaldehydes are products of broad commercial interest and are used as end products and intermediates in flavor and fragrance applications and pharmaceutical ingredients. For example, 3,4-methylendioxy-benzaldehyde (also known as heliotropin or piperonal) is used widely both as a end product and intermediate for the above mentioned applications. Other examples include 3,4-dimethoxybenzaldehyde, 3,4,5-trimethoxybenzaldehyde and 3,4-ethylenedioxybenzene which are intermediates in the synthesis of active pharmaceutical intermediates.

标 题 :Optimized synthesis of pregabalin and 4-aminobutane acid using an improved method for producing conjugated nitroalkenes
发明人：STUMPF MARCUS
权利人:K H S PHARMA HOLDING GMBH
摘要:The invention relates to an optimized synthesis of pregabalin and additional 4-aminobutane acids using an improved method for producing conjugated nitroalkenes. This is achieved by a nitro-aldol reaction of an aliphatic aldehyde with a nitroalkane in the presence of a suitable diamine directly followed by an elimination of the conjugated nitroalkene by adding an acid, a subsequent catalyzed asymmetrical 1,4-Michael addition of a suitable nucleophile, and a subsequent retro-Claisen reaction or a hydrolosis and decarboxylation with a concluding reduction to 4-aminobutane acid.

标 题 :Biocatalytic synthesis of strained carbocycles
发明人：CHEN KAI; HUANG XIONGYI; KAN S B JENNIFER
权利人:CALIFORNIA INST OF TECHN
摘要:Provided herein are methods for producing products containing strained carbocycles, such as cyclopropene moieties and/or bicyclobutane moieties. The methods include combining an alkyne and a carbene precursor in the presence of a heme protein, e.g., a cytochrome P450, under conditions sufficient to form the strained carbocycle. Reaction mixtures for producing strained carbocycles are also described, as well as whole-cell catalysts comprising heme proteins and variants thereof for forming cyclopropenes, bicyclobutanes, and related products.
