PMK ethyl glycidate Usage And Synthesis

Description

PMK ethyl glycidate is an analytical reference standard categorized as a precursor in the synthesis of methylenedioxy phenethylamines and amphetamines, including 3,4-MDMA. This product is intended for research and forensic applications.

Uses

NSC 195099 can be used as an analytical reference standard.

Application

PMK methyl glycidate is applied as immediate precursors of 3,4-methylenedioxymethamphetamine. 

Synthesis

To a solution of piperonal (1, 3.00 g, 19.9 mmol) in CH2Cl2 (100 mL) was added (carbethoxyethylidene)triphenylphosphorane (2,14.5 g, 40.0 mmol), and the reaction mixture was stirred for 24 h at room temperature. The mixture was then concentrated at reduced pressure, and the residue was purified by flash column chromatography on silica gel (hexanes/EtOAc,10:1) to afford olefin 3 (4.45 g, 95%) as a colorless oil: 1H NMR (400 MHz, CDCl3) d 7.58 (s, 1H), 6.92 (d, J = 1.7 Hz, 1H), 6.90 (dd, J = 7.9, 1.7 Hz, 1H), 6.82 (d, J = 8.0 Hz, 1H), 5.97 (s, 2H), 4.24 (q, J = 7.1 Hz, 2H), 2.10 (d, J = 1.6 Hz, 3H),1.33 (t, J = 7.1 Hz, 3H); 13C NMR (100 MHz, CDCl3) d 168.7,147.6, 138.3, 129.9, 126.9, 124.6, 109.5, 108.2, 101.2,  60.7, 14.3,1 4.0; IR (ATR, cm-1): 2981, 2902,1698, 1628, 1502, 1489,1442, 1258, 1224; HRMS (EI) m/z calcd for C13H14O4 (M+) 234.0892, found 234.0895.
