The N-Cyclopropylimine-1-pyrroline Photorearrangement as a Synthetic Tool: Scope and Limitations
摘要:
[GRAPHICS]The scope and limitations of the photorearrangement of N-cyclopropylimines to 1-pyrrolines are presented. The influence on the reactivity of different substituents throughout the cyclopropane ring and at the iminic position of the N-cyclopropylimine structure is discussed. The observed effects are interpreted from computational studies. The principal findings relate to (1) the enhanced reactivity of 1-substituted compounds toward rearrangement, (2) the lack of reactivity of crowded cyclopropanes, and (3) the high chemoselectivity of the process.
Regioselective palladium (O) catalyzed azidation and amination of 1-alkenylcyclpropyl esters: a new route to 2,3-methanoamino acids.
摘要:
Palladium (0) catalyzed azidation of 1-alkenylcyclopropyl esters provides regioselectively 1-azido-1-alkenyl cyclopropanes, convenient precursors of 2,3-methanoamino acids. On the other hand, amination occurred exclusively on the less substituted allylic end, providing strained 2-cyclopropylideneethylamine derivatives.

The reaction of various aromatic nitriles with 1.1 equiv of Ti(Oi-Pr)(4) and 2.2 equiv of EtMgBr followed by addition of a Lewis acid gave 1-aryl cyclopropylamines in 43-76% yields. Under similar conditions, conjugated alkenenitriles afford 1-alkenylcyclopropylamines (42-65%).
Provided are novel compounds of Formula (I):
and pharmaceutically acceptable salts thereof, which are useful for treating a variety of diseases, disorders or conditions, associated with LSD1. Also provided are pharmaceutical compositions comprising the novel compounds of Formula (I), pharmaceutically acceptable salts thereof, and methods for their use in treating one or more diseases, disorders or conditions, associated with LSD1.
