Asymmetric Synthesis of 2°- and 3°-Carbinols via B-Methallyl-10-(TMS and Ph)-9- borabicyclo[3.3.2]decanes
[Image: see text] Simple Grignard procedures provide methallylboranes 1a and 1b in enantiomerically pure form from air-stable precursors in 98% and 95% yields, respectively. These reagents add smoothly to aldehydes and methyl ketones, respectively, providing branched 2°-(6, 69–89%, 94–99% ee) and 3°...
