In 1978, we found2' a photoisomerization of troponoids under a-and P-cyclodextrin (CDX)-included conditions to give bicyclo(3.2.0]hepta-3,6-dien-2-ones with a remarkable rate enhancement and with much improved yields for proto-photoisomers in various dispersion media.

The findings will be described in this paper.

The above mentioned readines$ in furnishing the cyclopentene synthons prompted us to carry out the experiments on the synthesis of this methylene cyclopentanone relative, methyl ester of bis(dehydroxyl) derivative (4) of A'O' as follows. Prolonged irradiation of lb under the B-CDX-inclusion conditions in cyclohexane afforded optically active 5'i' via the proto-photoisomer (2),i2' 1-methoxyl isomer, in 470/o yield with 550/o enantiomeric excess. Optical activities of these compounds were determined by derivation to 3oxocyclopentaneacetic acid (6).

This study is intended to provide one of data bases for a large-scale MHD generator. The steady one-dimensional conservation equations, coupled with the Ampere's law and the generalized Ohm's law, are solved. It has been shown that, in the case of a divergent channel and that a loading factor is constant, the limiting length of channel for choking decreases with an increase in an interaction parameter. A shock wave appears in a divergent channel for a certain range of the interaction parameter. The minimum value increases with an increase in the loading factor and with a decrease in the friction coefficient, but it is almost independent of the inlet Mach number of the channel. On the other hand, the maximum value increases with increases in the loading factor and in the inlet Mach number, but it is almost independent of the friction coefficient.","PeriodicalId":11722,"journal":{"name":"Engineering sciences reports, Kyushu University","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1985-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81651023","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
