New route to enantiomerically pure 4,4-Disubstituted cyclohex-2-en-1-ones: Asymmetric synthesis of (+)-mesembrine

Autor: Hiroshi Kosugi, Hisashi Uda, Yasuyuki Miura, Hiroshi Kanna

Publikováno v: Tetrahedron: Asymmetry. 4:1409-1412

Enantiomerically pure β,β-disubstituted vinyl sulfoxides undergo cycloaddition with dichloroketene to give β,β-disubstituted γ-lactones which are transformed into synthetically important 44-disubstituted cyclohex-2-enones in optically pure form.

Autor: Chun-Ping Chu, Wen-Zhe Jin, Yan-Hua Bing, Qing-Hua Jin, Hiroshi Kannan, De-Lai Qiu

Publikováno v: PLoS ONE, Vol 8, Iss 1, p e53863 (2013)

The effects of stresscopin (SCP) on rat paraventricular nucleus (PVN) neurons were examined using whole-cell patch-clamp recordings and single-cell reverse-transcription multiplex polymerase chain reaction (SC-RT-mPCR) techniques. Under current-clamp

Highly enantiospecific synthesis of 4-alkyl and 4,5-dialkyl substituted 4,5-dihydrofuran-2(3H)-ones from optically active (E)- and (Z)-alk-1-enyl p-tolyl sulphoxides: application to the synthesis of lignan lactones

Autor: Katsuya Tagami, Hiroshi Kosugi, Hisashi Uda, Akira Takahashi, Hiroshi Kanna

Publikováno v: Journal of the Chemical Society, Perkin Transactions 1. :935

Stereochemically and optically pure 2-substituted ethylenic p-tolyl sulphoxides (R)-E-(4) and (R)Z-(4) undergo readily and stereospecifically an additive Pummerer rearrangement reaction with dichloroketene to give trans- and cis-β-alkyl-α,α-dichlo
