摘要:
Reduction in cooling rate of a substrate having a lower temperature is suppressed because the substrate having a lower temperature is not affected by radiant heat of a substrate having a higher temperature while cooling a plurality of substrates in a cooling chamber. The substrate processing apparatus includes a load lock chamber configured to accommodate stacked substrates; a first transfer mechanism having a first transfer arm provided with a first end effector, and configured to transfer the substrates into/from the load lock chamber at a first side of the load lock chamber; a second transfer mechanism having a second transfer arm provided with a second end effector, and configured to transfer the substrates into/from the load lock chamber at a second side of the load lock chamber; a barrier installed between the substrates to be spaced apart from the substrates supported by a substrate support provided in the load lock chamber; and an auxiliary barrier unit installed between the substrate support and the barrier, wherein the auxiliary barrier unit is installed at places other than standby spaces of the end effectors.
摘要:
An optically active spirolactone compound is highly enantioselectively produced by using an iodoarene derivative which can be synthesized easily and which is not racemized easily. A hypervalent iodine compound precursor (iodoarene derivative) which was able to be designed flexibly was synthesized from 2,6-dihydroxyiodoarene by using 1,2-aminoalcohol as a chiral source in short steps, a hypervalent iodine compound was prepared in a reaction system (in situ) by using a catalyst quantity of the resulting precursor in the presence of a stoichiometric quantity of m-CPBA, and a spirolactonization reaction of 3-(1-hydroxy-2-naphthyl)propionic acid was induced. As a result, a corresponding spirolactone compound was obtained at a high enantiomeric excess.
