Calculate Digit Verification of CAS Registry Number 187663-91:
(8*1)+(7*8)+(6*7)+(5*6)+(4*6)+(3*3)+(2*9)+(1*1)=188
188 % 10 = 8

Synthesis of α-necrodol: Unexpected formation of a cyclopropene

Taber, Douglass F.,Yu, Han

, p. 1687 - 1690 (2007/10/03)

Significant 1,3-induction in intramolecular alkylidene C-H insertion is reported. Thus, exposure of ketone I to the lithium salt of (trimethylsilyl)diazomethane provides a 2.4:1.0 ratio of IIa and IIIa, which are deprotected to α-necrodol IIb and the epimeric IIIb. The 1,3-insertion product cyclopropene IV was also formed.
