User reports indicate that ephylone produces a mixture of classic stimulant and entactogenic effects resembling those of MDMA, methylone and cocaine. Typical effects include stimulation, disinhibition, increased libido, compulsive redosing, and euphoria. Unlike similar substances, however, ephylone is reported to be very long lasting when taken in larger doses. The significance of this is not known, although it may indicate that it has a different toxicity profile compared to other stimulants.
Ephylone is sold online as a research chemical alongside other synthetic cathinones like ethylone and dibutylone. Due to the lack of research, it is highly advised to use harm reduction practices if using this substance.

Tert-Butyl (1-(hydroxymethyl)cyclopropyl)carbamate could be converted into spirocyclopropanated analogues 14-CP and 14-CT of the insecticide Thiacloprid [1]. It can also be transformate of into spirocyclopropanated analogues of Imidacloprid.

Tert-Butyl (1-(hydroxymethyl)cyclopropyl)carbamate can be synthesized in three steps (40 % overall yield) from N, Ndibenzyl-2-benzyloxyacetamide starting with its reductive cyclopropanation (the de Meijere variant of the so-called Kulinkovich reaction). It can also be prepared in 56 % overall yield by monohydrolysis of commercially available diethyl cyclopropane-1,1-dicarboxylate followed by Curtius degradation of the carboxylic acid residue and subsequent reduction of the ester moiety[1].

General procedure for the synthesis of (1-hydroxymethylcyclopropyl)-tert-butoxycarbonylamino acids from ethyl 1-(BOC-amino)cyclopropanecarboxylate: ethyl 1-((tert-butoxycarbonyl)amino)cyclopropanecarboxylate (4.31 g, 18.80 mmol) was dissolved in tetrahydrofuran (THF, 20 mL), and a 2M lithium borohydride (LiBH4) THF solution was slowly added dropwise ( 10.34 mL, 20.68 mmol), and the reaction mixture was stirred at room temperature overnight. Subsequently, a THF solution of 2M LiBH4 (5 mL, 10 mmol) was added additionally and stirring was continued at room temperature for 6 hours. Upon completion of the reaction, anhydrous sodium sulfate (Na2SO4, 15 g) and water (H2O, 10 mL) were added and the suspension was stirred at room temperature over the weekend. The suspension was filtered through a pad of sodium sulfate and the residue was washed with dichloromethane (DCM). The combined filtrates were concentrated under reduced pressure and the product was purified by column chromatography (silica gel, heptane/ethyl acetate, 1:1) to give 2.78 g of the target product in 79% yield.
