Catalytic effect of a BH3: N,N-diethylaniline complex in the formation of alkenyl catecholboranes from alk-1-ynes and catecholborane

TL;DR: The continued development of hydroboration catalysts typifies the importance of this transformation as a testbed for catalytic activity and as a fundamental reaction for organic synthesis as discussed by the authors, and they have been widely used in the literature.

TL;DR: In this article, a coupling reaction of 1,3-disubstituted secondary allylic carbonates with lithium aryl-and alkenylborates in the presence of a nickel catalyst is described.

TL;DR: In this paper, a new synthesis of retinol (vitamin A) and 9- and/or 13-demethylretinols, with essentially complete control of regio- and stereochemistry, is described.

TL;DR: The polyene antibiotic myxalamide A has been prepared by total synthesis and illustrates a useful strategy for synthesis in which the high 1,2-stereocontrol achievable with the aldol reaction can be parlayed by other stereoselective processes so as to give compounds having two or more stereocenters with remote relationships.
