The invention relates to new indole derivatives, their preparation and use as drugs. Said compounds may be represented by the general formula ##STR1## in which R represents a hydrogen atom or an alkyl or benzyl group and Z represents a hydrogen atom or a halogen atom or an alkyl, hydroxy, acyloxy, carbamate or methoxy group. They are prepared by reacting tryptamine derivatives with synthons of the formula ##STR2## in which X and Y each represent an oxygen or sulphur atom, and R.sub.1 and R.sub.2 each represent an alkyl or phenyl radical or form together an alkylidene chain. They may be used as intermediate compounds for chemical syntheses and also as drug for treating cerebro-vascular and cardio-circulatory insufficiencies.
An efficient Ni–(S,S)-Ph-BPE complex that catalyzed asymmetrichydrogenation of cyclic N-acyl hydrazones has been developed to produce various chiral cyclic hydrazines in high yields with excellent enantioselectivities of up to >99% enantiomeric excess. Moreover, the hydrogenation can not only proceed smoothly on a gram scale under lower catalyst loading (S/C = 3000) without any decrease of enantioselectivity
已开发出一种高效的 Ni-( S , S )-Ph-BPE 络合物,可催化环状N-酰基腙的不对称氢化,以高产率生产各种手性环状肼,具有高达 >99% 对映体过量的出色对映选择性。此外,氢化不仅可以在较低的催化剂负载量(S/C = 3000)下顺利进行,而且对映选择性没有任何降低,而且还可以应用于 RIP-1 激酶抑制剂的不对称合成。
