  Allyl boron derivatives are valuable building blocks in the synthesis of natural products and bioactive molecules. Herein, a practical strategy of nickel-catalyzed highly selective hydroalkenylation of alkenyl boronic esters was developed. Under the mild reaction conditions, a variety of allyl boronic esters were accessed with excellent chemo- and regioselectivity. The mechanism of this transformation

  The metal hydride reduction products of some styryl ketones and dimethylaminomethyl Mannich bases have been investigated. Sodium borohydride selectively attacked the carbonyl carbon atom to give the desired allylic alcohols. Reduction of 1-phenyl-1-nonen-3-one with lithium aluminum hydride gave 1-phenyl-3-nonanol which represents the conjugate addition product. Fragmentations of 1-phenyl-1-nonen-3-ol were compared to the modes of mass spectral breakdown of 4-phenyl-3-buten-2-ol, an allylic alcohol which is known to behave like a saturated ketone on electron bombardment. Peaks corresponding to the McLafferty ion and the loss of a methyl radical from this rearrangement product were observed. Certain Mannich bases were reduced to diastereoisomeric allylic amino alcohols. The separation, ¹H n.m.r. spectroscopy, and relative stereochemistry of the diastereoisomers are discussed.
