土地區劃整理事業의 施行上 改善方案에 관한 硏究 : on the cases developed by land owner's association 組合施行을 中心으로

1. Land Subdivision Project [LSP] was retreated in Korea, because of various special laws, that is, land Development Promotion Law, Housing Development Promotion Law, and so on. Even though these special laws make urban development project disarrange, Land Subdivision Project should be executed with priority. 2. Minister of Construction & Transportation would rather submit LSP to local government, by doing so the execution and the procedure of project is not complicated. 3. The special law for local land development must be amended for these reasons : ① the special charge on farm land developed by LSP, which amount to 20% of the officially evaluated land value is burdened. ② in this ISP, the special charge on farm land is not subtracted. ③ the provision of cheap housing land is impossible. 4. For more effective contribution to land development by LSP many related regulations in the law which enable LSP to exist must be also amended soon.

Tigers are the large cats with prominent, black or brawn, stripes. They are common in jungles of India and Java, but range as far as the snowy, forested mountains of Siberia. Legal and illegal killing(over-hunting, poaching for skin, and also its bones, f

The older zoos were parks with fenced enclosures and buildings containing caged animals. But animals in bare cages are not very the natural environment in which an animal or a group of animals is found. In some displays, the animals appear to be living to
키랄 보조제로서의 C<sub>2</sub>-대칭성 피롤리딘 아미드의 합성과 광학 순도 결정

쉽게 얻을 수 있는 1,2:5,6-di-O-isopropylidene-D-mannitol (1)로부터 $C_2$-대칭성 피롤리딘 아미드 (8)을 합성하였다. 벤질 아민과 dimesylated hexitol (4)를 고리화 반응 시키면 트랜스 형태의 $C_2$-대칭성 피롤리딘 아민(5)가 주생성물로 얻어지나, 이와 함께 이성질화가 일어나 시스 이성질체인 화합물(6)도 생성된다. 피롤리딘 아민 (5,6)을 탈보호된 아민 (7)을 거쳐 아미드 (8,9)로 변형시켜 이를 순수한 형태로 분리하고, 이 $C_2$-대칭성 피롤리딘 아미드(8)의 광학 순도를 측정하기 위해 Mosher 유도체(13,14)를 합성하였다.$^1H$ 과$^{19}F$ NMR 실험으로 Mosher 유도체 (13,14)가 단일 물질임이 밝혀졌고, 이로서 피롤리딘 아미드 (8)이 광학적으로 순수한 화합물임을 확인하였다. Optically pure $C_2-Symmetric$ pyrrolidine amides (8) were synthesized from readily available 1,2:5,6-di-O-isopropylidene-D-mannitol (1). Cyclization of dimesylated hexitol (4) with benzyl amine gave an inseparable mixture of $C_2-Symmetric$ pyrrolidine amine derivative (5) as a major product, concurring with its cis isomer (6) as a minor product. The pyrrolidine amines (5,6) were converted to separable pyrrolidine amides (8,9) via free amine (7). Optical purity of desired $C_2-Symmetric$ pyrrolidine amide (8a) was determined with its Mosher derivatives (13,14) by their $^1H$ and $^{19}F$ NMR spectra.
