Regioselective Ni(II)-assisted alkylation of 2-methoxy-5,6-dihydro-2H-pyran: a new route to 2-n-alkyl-5,6-dihydro-2H-pyrans
摘要:
In the presence of a catalytic amount of NidppeCl(2), 2-methoxy-5,6-dihydro-2H-pyran reacts with primary Grignard reagents to give the corresponding 2-n.alkyl-5,6-dihydro-2H-pyrans in satisfactory yields. (C) 1998 Elsevier Science Ltd. All rights reserved.
