Wittig Rearrangement of Nonracemic Propargyl Ethers Leading to Allenes of High Stereochemical Integrity
Marshall, James A.,Robinson, Edward D.,Zapata, Antonio
, p. 5854 - 5855 (2007/10/02)
The (R)-propargylic tributylstannylmethyl and glycolic acid ethers 4a, 4b, 5a and 5b rerrange to the (R)-allenylcarbinols 6a, 6b, 7a, and 7b of high ee upon treatment with n-BuLi or LDA, respectively, at low temperature.
