In our study on the synthesis of glucosaminides we have employed 2,4-dinitropheuyl group (DNP) to protect the amino group of glucosamine, and foundthat DNP substitution brings forth an anomalous change in the optical rotation. By following Kent's procedure we obtained from 2-amino-2-deoxy-D-glucose hydrochloride (Ⅰ) N-DNP-2-amino-2-deoxy-D-glucose (Ⅱ). Its meltingpoint, 194°(200--202°, Kofler block), agrees with that reported by Meyer et al.(196±2°) and Morgan et al. (202-4°), but differs from that given by...

In our study on the synthesis of glucosaminides we have employed 2,4-dinitropheuyl group (DNP) to protect the amino group of glucosamine, and foundthat DNP substitution brings forth an anomalous change in the optical rotation. By following Kent's procedure we obtained from 2-amino-2-deoxy-D-glucose hydrochloride (Ⅰ) N-DNP-2-amino-2-deoxy-D-glucose (Ⅱ). Its meltingpoint, 194°(200--202°, Kofler block), agrees with that reported by Meyer et al.(196±2°) and Morgan et al. (202-4°), but differs from that given by Kent(167-9°). The specific rotation values reported by all workers being practicallythe same([α]_D~(23)+50°; [α]_(5463)~(23)+68.7° in 80% ethanol). Acetylation of (Ⅱ) withacetic anhydride and pyridine gave a tetra-acetyl derivative (Ⅲ). Its meltingpoint (214-5°) and [α]_D~(20)(+12°, CHCl_3) also differed from those given by Kent(159-60°; [α]_D~(19)+73°, CHCl_3). (Ⅲ) was nearly quantitatively converted into1-bromo-3, 4, 6-tri-O-acetyl-N-DNP-2-amino-2-deoxy-α-D-glucose (Ⅴ) in usualway. Compound (Ⅴ) is identical with Stacey's bromo-compound (m. p. 162-4°[α]_D~(19)+46.0°, CHCl_3), obtained from another tetraacetyl-N-DNP-derivative (Ⅳ).Since (Ⅳ) was derived from the known 1, 3, 4, 6-tetra-O-acetyl-2-amino-2-deoxy-β-D-glucose (Ⅵ), and (Ⅲ) has also been prepared by us from 1, 3, 4, 6-tetra-O-acetyl-2-amino-2-deoxy-α-D-glucose hydrobromide (Ⅶ) of well establishedα-configuration, these two DNP-compounds (Ⅲ and Ⅳ) should form a pairof α- and β-anomers. Merely on the basis of Hudson's isorotation rule, it shouldbe predicted that (Ⅳ) wore tho α- and (Ⅲ) the β-anomer, which are contradictoryto their configurations as expected from the starting materials used. In order toconfirm the configuration of the C_(1)-atom of the compounds in question, otherpairs of DNP-derivatives of glncosamine, such as (Ⅷ) and (Ⅸ), (Ⅹ) and (Ⅺ),together with (Ⅻ) and (ⅩⅢ) were prepared according to the methods sketchedin Fig. 1. Melting points and specific rotations of these products are presentedin Tablo Ⅰ. Since (Ⅸ) and (Ⅺ) possess higher values of [α]_D than the correspondinganomers (Ⅷ and Ⅹ), (Ⅸ) and (Ⅺ) would be assigned as α-glucosaminides and(Ⅷ) mid (Ⅹ) as the β-anomers, if Hudson's isorotation rule were also applicableto N-DNP-glucosamine derivatives as usual. However, after removal of DNP-groupwith barium hydroxide, (Ⅺ) yielded the known methyl-β-D-glucosaminide (ⅩⅢ)and (Ⅹ), the corresponding α-D-glucosaminide (Ⅻ) (Ⅻ). The configurationsof (Ⅹ) and (Ⅺ) have been further confirmed by direct syntheses of these anomersfrom tho known methyl N-acetyl-α-and β-D-glucosamindes (ⅩⅠⅤ and ⅩⅤ). Con-sequently, (Ⅷ) and (Ⅹ) must be α-type, and (Ⅸ) and (Ⅺ) β-type. The N- DNP-substitution causes an anomalous change in the rotatory power, so that thesubstituted β-glucosaminides are considerably more dextro-rotatory than the cor-responding α-anomers. From Table Ⅰ, it is clear that the differences between the molecular rotations[M]_D of the anomeric pairs (Ⅲ) and (Ⅳ), (Ⅷ) and (Ⅸ) its well as (Ⅹ) and(Ⅺ), (i. e. 2A values) are all negative in sign, while the 2A values for anomericD-glucosamines, D-glucosamine hydrochlorides, pentaacetyl-D-glucosamines andmethyl-D-glucosaminides hydrochlorides are all positive. The 2B values of N-DNP-substituted products have the same sign and nearly the same magnitudeas those of the ordinary anomeric glucosamine derivatives. Thus DNP groupat C_(2)NH_2 has greater influence on the [M]_D of C_(1)-atom than on that of theremaining part of the molecule. This vicinaI effect of DNP-substitution on [M]_Dof the C_(1)-atom may be (i) due to change in polarity , (ii) due to increasein the number of conjugated double bonds (or shift in the absorption bands ofthe substituent, or (iii) due to steric interaction between vicinal substituensof the molecule.

在2-氨基-2-脱羟-D-葡萄糖的氮原子上引入2,4-二硝苯基后,其旋光性有显著的变化。自2-氨基-2-脱羟-D-葡萄糖(Ⅰ),我们获得一新的四乙酰-N-二硝苯基衍生物(Ⅲ), 该物经证明系属于吡喃糖α-型,但其旋光率比其β-端基差向异构体(Ⅳ)更向左旋,而与一般糖类α-与β-异构体之间的旋光率的关系不符。我们再观察N-二硝苯-2-胺基-2-脱羟-D-葡萄糖甲甙及其乙酰衍生物的α-与β-异构体的旋光率,也有相同的反常现象。 Hundson同旋律不完全适用于以上的N-二硝苯-D-胺基葡萄糖及其衍生物的原因可能由于C_(2)原子上N-二硝苯基对邻位C_(1)旋光性的影响所致。

A computer method was developed for the non-linear full-range analysis of reinforced concrete columns from the start of loading to the collapse of column. This is an extension of W.B.Cranston's work,which has the merit of not requiring computations of M-P-(?) curves. For the sake of speedy convergence, the Chebyshev's approximate integration has been used and a set of formulae has been derived for various cross sections of columns.This method can describe more accurately the behavior in the full range of loading and unloading of pin-connected columns with equal or different eccentricities at both ends. The effect of creep of concrete and that of prestressing have been taken into account in the analysis. The comoarison of calculation and experimental results agree satisfactorily.

本文提供一个对钢筋混凝土柱从加荷开始至混凝土压坏全过程的非线性分析方法。它是W.B.Cranston工作的延伸。为减少循环次数采用了Chebyshev近似积分并推导了适用于各种柱截面的一套计算公式。该法可较准确地描述两端铰接不等偏心柱加荷的全过程,不仅考虑了混凝土徐变也考虑了预应力的影响。该法可毋须计算M-P-φ曲线族,并可根据需要提高计算精度。计算与试验值比较结果,令人满意。
