    摘要： When a multi-step process reaction is carried out in a solution, it generally requires several treatments and purification procedures to go through with after the reaction, however, the inventive method for preparing 2,2′-disubstituted-3,4-dihydro-7,8-disubstituted-6-amino benzopyran derivative using a solid-phased synthetic method simplifies the treatment and purification procedures after the reaction, which makes possible to efficiently construct numerous drug-like libraries. In particular, since the inventive method of the present invention comprises the steps of introducing a carbonate linker of formula 2 into Wang resin used as a common solid support (Step 1); synthesizing various benzopyran in a carbamate form of formula 3 as a key intermediate by reacting various amino benzopyran derivatives with the carbamate resin of formula 2 (Step 2); synthesizing 2,2′-disubstituted-3,4-2H-6-substituted benzopyran resin of formula 4 (Step 3); and synthesizing 2,2′-disubstituted-3,4-2H-6-alkylamino benzopyran derivative of formula 1 using a dichloromethane solution containing TFA or an organic solvent containing an organic acid, the inventive method is capable of efficiently synthesizing various 2,2′-disubstituted-3,4-2H-6-alkylamino benzopyran derivatives.Consequently, the present invention has developed a new technique for constructing 2,2′-disubstituted-3,4-2H-6-alkylamino benzopyran library using a solid-phase parallel synthetic method and makes increased the applicability of combinatorial chemical synthetic method. Further, 2,2′-disubstituted-3,4-2H-6-alkylamino benzopyran derivative prepared by the inventive method has a high inhibitory effect to 5-lipoxygenase (5-LO) activity, and therefore, can be effectively used for developing a new propylactic or therapeutic drug for leukotriene activation-related diseases such as chronic inflammation, rheumatic arthritis, colitis, asthma and psoriasis.

    摘要： An apparatus and method for measuring a three-dimensional shape of an object using a projection moiré device. The method comprises the steps of obtaining a grid pattern image projected on a reference plane of a moving table and applying a buckets algorithm thereto, thereby achieving a reference phase, obtaining a grid pattern image projected on the object set on the moving table and applying a buckets algorithm thereto, thereby achieving an object phase, calculating a difference phase between the object phase and the reference phase, thereby achieving a moiré phase, and unwrapping the moiré phase, thereby achieving a level information of the object. The apparatus and method measure the three-dimensional shape using a projection grid without a reference grid, thereby achieving compactness of equipment, simplicity in usage and manufacturing cost reduction.
