Calculate Digit Verification of CAS Registry Number 189348-98:
(8*1)+(7*8)+(6*9)+(5*3)+(4*4)+(3*8)+(2*9)+(1*8)=199
199 % 10 = 9

A convenient synthesis of alkynylpyrazoles

Yoshimatsu, Mitsuhiro,Kawahigashi, Masataka,Honda, Eiji,Kataoka, Tadashi

, p. 695 - 700 (2007/10/03)

Diazomethane add to the enyne sulfones 1,3,4,6-11 regio- and stereo-selectively to give the 4-alkynyl-5-phenylsulfonyl-4,5-dihydro-3H-pyrazoles 12-15 and 17-19, which are converted by MeLi into the 4-alkynyl-1H-pyrazoles 24, 25, 16, 26, 28, 30 in good yields. 4,5-Bis(alkynyl)-1H-pyrazoles 34, 37 are also obtained by the same procedure.
