Filed: 1984-06-05
Abstract: PURPOSE:To produce the titled compound useful as a hypotensor, in high yield, by reacting erythro-3-(3,4-methylenedioxyphenyl)serine with carbobenzoxy chloride, treating the reaction product with a Lewis acid, and subjecting to the catalytic reduction. CONSTITUTION:Erythro-3-(3,4-methylenedioxyphenyl)serine of formula I is made to react with carbobenzoxy chloride to obtain the compound of formula II, which is converted to the compound of formula III by treating with a Lewis acid (e.g. aluminum chloride). The resultant compound of formula III is catalytically reduced to obtain the objective compound of formula IV. When the compound of formula II is treated with a Lewis acid, only the methylene group of the methylenedioxy group is eliminated to obtain the compound of formula III in high yield irrespective of the presence of carboxyl group, carbamate group and hydroxyl group. The corresponding objective compound having racemic or optically active nature can be produced in high yield by the catalytic reduction of the compound of formula III in the presence of a catalyst (e.g. Pt).

Filed: 1988-05-16
Abstract: PURPOSE:To eliminate the incidence onto a photodetector for direct monitoring of the light of the different wavelength and to correctly control the output of a semiconductor laser by arranging an interference filter at the emitting window of the semiconductor laser. CONSTITUTION:An interference filter 29 to transmit selectively only the oscillation wavelength of a semiconductor laser 24 is arranged at an emitting window 23 of a semiconductor laser 3. Consequently, the interference filter 29 transmits only the wavelength of the light irradiated from a laser chip 24 in the internal part of the semiconductor laser 3, does not transmit the light of other wavelength, and therefore, it is prevented that the light of other wavelength is made incident on a photodetector 26 for monitoring in the internal part of the semiconductor laser 3 as leaking light and stray light. Thus, even when plural semiconductor lasers 3 different in wavelength are used simultaneously at the same optical system, plural semiconductor lasers 3 can be individually and correctly output-controlled.
