Synthesis of polysubstituted furans based on a stepwise Sonogashira coupling of (Z)-3-iodoalk-2-en-1-ols with terminal propargylic alcohols and subsequent Au (I)-or …
Recently, we have developed highly regio-and stereoselective carbometalation of 2- alkynols and 2, 3-allenols. The organometallacyclic intermediates may be trapped with I2 to afford 3-iodoalk-2-en-1-ols. These 3-iodoalk-2-en-1-ols may readily undergo the
