-
Paragraph 0017, (2017/09/29)
The invention discloses application of a piperazine structure containing compound to the preparation of a histone lysine specific demethylase (LSD1) inhibitor. The structural general formula of the compound is as shown in the following descriptions (wherein, A is hydrogen, carbonyl or thiocarbonyl) or a configurational isomer and a pharmaceutical salt thereof, or is as shown in the following descriptions or a pharmaceutical salt thereof. The compound has an obvious inhibition effect on the LSD1, can be prepared into the LSD1 inhibitor, and is used for preventing and treating a disease related to the activity of the histone LSD1.

Enantiomerically-enriched trichloromethyl-containing alcohols, obtained by asymmetric reduction, can be transformed regioselectively into 1-substituted piperazinones by modified Jocic reactions with little or no loss of stereochemical integrity. This meth

2,2,2-Trichloromethylcarbinols are 1 are valuable synthetic intermediates with a multitude of uses. A scalable procedure for the synthesis of TMS-protected-2,2,2-trichloromethylcarbinols and 2,2,2-trichloromethylcarbinols 1 was developed that employs the in situ generation and reaction of trimethyl(trichloromethyl)silane (CCl3-TMS). The procedure avoids the exposure of the carbonyl compounds to the strongly basic conditions typically used for this transformation and also avoids isolation of the difficult-to-handle CCl3-TMS. This procedure was applied to diastereoselective trichloromethyl additions to 2-substituted 4-piperidinones and to reactions with a variety of structurally diverse aldehydes and ketones.
