Syn-selective reduction protocols for β-hydroxy ketones are described exploiting the intermediacy of titanium and boron chelates derived from TiCl4 and BCl3, respectively. Reductions are conducted at −78 °C in CH2Cl2 using a wide range of CH2Cl2-

Catalytic quantities of transition metal alkoxides such as Ti(O i Pr) 4 have been found to accelerate dramatically the rate of catecholborane and BH 3 ·THF reductions of ketones. Experiments suggest catalysis is achieved by the formation of alkoxybo

The reduction of salicylaldehyde by pyridine-borane complex (PB) is much faster than that of other substituted benzaldehydes and ketones (seconds vs hours). Experiments reveal that this acceleration is due to an autocatalytic process involving a pyri

Many years ago Diels and Thiele noted the unusual stability of maleic anhydride cycloadducts and employed the feature in scavenging anthracene generated in a retro-[4+2] reaction. N-methyl-maleimide, although nearly identical to maleic anhydride in r
