A one-pot preparation of unsymmetrical 1,4-alkynediols such as 2a by the coupling of trimethylsilylacetylene and two different aldehydes or ketones is reported. The dilithiated species 5 is generated by the sequential addition of the first aldehyde o

The first enantioselective synthesis of a chamigrane sesquiterpene, (+)-majusculone, has been completed. The quaternary center was generated asymmetrically by alkylidene carbene insertion, with retention of absolute configuration, from a diastereomer

The preparation of an advanced intermediate toward the enantioselective synthesis of tetrodotoxin is outlined. The enantiomerically pure cyclopentene 15 was generated from ketone 14 by alkylidene carbene insertion with retention of absolute configura
