A convergent synthesis of the C(18)-C(34) fragment of amphidinolide C and the C(18)-C(29) fragment of amphidinolide F is reported. The approach involves the synthesis of the common intermediate tetrahydrofuranyl-β- ketophosphonate via cross metathesis, Pd

Following studies using benzyloxymethyl isopropenyl ketone 5 and ethyl 3-(3-furyl)-3-oxopropanoate 6, Robinson reactions between aryloxymethyl isopropenyl ketones 19 and 5 and ethyl 3-(2-trimethylsilyl-3-furyl)-3- oxopropanoate 20 were found to be stereos

The stability order of various alkyl, allyl, and benzyl carbocations was investigated using the novel technique for comparing the stability of carbocations in solution developed by using a simple CSI reaction with various ethers. The p-methoxycinnamyl carbocation was the most stable in our reaction system and the next stable carbocation was the p-methoxybenzyl carbocation. The stability of the other carbocations decreased with methacryl, t-butyl, cinnamyl, acryl, benzyl, 2° and allyl carbocations in that order.
