functionalized 1,3‐diol derivatives is reported. Employing a copper‐catalyzed oxy‐alkenylation strategy, a range of readily available, substituted homoallylic alcohol derivatives and alkenyl(aryl) iodonium salts combine to form syn‐1,3‐carbonates in excellent yield and with high selectivity. Furthermore, the products formed are amenable to an iterative reaction sequence, thus affording highly complex polyketide‐like

base and aromatic, followed by deprotonative formation of the functionalized aromatic aluminum compound. Deprotonation by the TMP ligand rather than the isobutyl ligand was suggested and reasoned by means of spectroscopic and theoretical study. The remarkable regioselectivity of the ortho alumination reaction was explained by a coordinative approximation effect between the functional groups and the counter

The first manganese(I)‐catalyzed C−H allylations with ample scope were achieved by carboxylate assistance. The highly selective C−H/C−O functionalizations proved viable with densely substituted allyl carbonates, and the organometallic C−H allylation strategy set the stage for expedient late‐stage diversification with excellent levels of positional selectivity.

P(NR2)3, have been used as a source of carbamate groups in the reaction with alkyl halides, R′X, to afford carbamateesters. The reaction is mediated by alkali-metal halides, MY, and requires the presence of a suitable macrocyclic polyether (L). The overall reaction occurs in two steps: the carbamic group is first transferred to the alkali-metal cation to give a carbamate salt [ML][O2CNR2] which then reacts
